Borderlands is shit - DEBATE!
I know you're joking, but I have loads to say about that, so I will
Borderlands isn't shit, but it does have some huge failures.
The first problem I have with Borderlands is that as a single-player game, there's not enoguh atmosphere. When you're playing co-op, there's just enough character and charm to the world and everyone in it. But when you're playing co-op, you're just a tourist, breezing through the world with your friends. You might enjoy the scenery and half-listen to whatever is going on around you, but primarily you're chatting with each other, making jokes and keeping things interesting.
Single player is a whole other story. Instead of being a tourist in a group, you're living in this world, so the story, the characters and the locations are all you have to keep things interesting. This is where Borderlands fails, because what's there is generally all too shallow and painted on. I think that's the primary reason that a lot of people didn't end up liking Borderlands. Luckily, Borderlands 2 is far more interesting. The world has so much more fleshing out. Characters from the first game come back and have interesting things to say and do, but more importantly, they've developed relationships with each other so everything seems more dynamic. New characters like Tiny Tina and Handsome Jack may seem to exist in a vaccuum, but at least they've been shoved full of jokes and, in Tiny Tina's case, a pretty dark side-story about why she's an orphan and how fucked up it's turned her.
Another key problem with Borderlands is that the reality of NEAR INFINITE GUNS!!!! isn't half as cool as the promise. If you're lucky enough to find something that's actually useful to you before level 15 then you're doing well, and you'll probably love the game. That's not always the case, though. My first character, the Siren got some pretty sweet SMGs early on, so I had a blasty-blast playing her. As she levelled up, there were obviously more guns to find and choose from, so it just ramped up and up.
In contrast, my second playthrough was with the Soldier. I just wanted a decent shotgun and/or a decent assault rifle. I didn't find ANYTHING I wanted to use until about level 20, so I was stuck with a pistol and an SMG that "were kind of OK". This absolutely ruined my enjoyment for hours because I never felt like a badass shootybanger, which is the whole point of Borderlands. Again, as I levelled up more guns were available which means the problem went away, but it's a shitty way to introduce players into the game. If this happened on my first playthrough, I doubt I would've carried on and I definitely wouldn't have bought Borderlands 2 sight unseen.
Unfortunately, Borderlands 2 doesn't really fix this issue too well. Once again, it all comes down to luck, though I will say that B2 DOES seem to throw a lot more guns at you, giving you a better chance of finding something serviceable early on. Though having so many guns available early on can be a bit daunting, especially if you skipped the first game due to all of the issues.
The last problem I have with Borderlands, and this absolutely didn't get fixed in the second game, is the vehicle stuff. It's supposed to feel like Mad Max, right? I'm pretty sure it is. The only reason I'm so confused is because it totally doesn't feel like Mad Max.
Vehicles control horribly on mouse & keyboard. Something I can understand as the game is just a port, but to be honest, they control like shit on a gamepad too. It's laborious and annoying. I'm genuinely not sure how it didn't come up in ALL the playtests that this shit desperately needed to change.
Aside from the actual controlling of the vehicles, I hate how easily and how stupidly vehicles can become stuck on terrain. It feels like an early PS2 game when you're driving along and come to a SUDDEN STOP because you clipped a rock or a bush. What the fuck?! At least let me bounce off of the fucking thing?
Then we come to the vehicle combat. Did I mention laborious? I actually ended up getting out of the car and blasting the fuckers with grenades and a rocket launcher just to avoid it. It doesn't help that any kills you do in a vehicle give you less XP, which just says "don't bother with vehicle combat" to me.
So, with all of these negatives, how can I say that Borderlands is a great game? Because it absolutely is... with a slight condition.
Borderlands is a GREAT co-op game.
Everything comes together - good and bad points about the game - beautifully to make this incredibly fun to play with friends.
The shitty vehicle controls go from frustrating to hilariously enjoyable because you can berate each other when you fuck up and probably more importantly, you can make somebody else drive.
The lack of weapons isn't a problem, because it introduces a fun trading dynamic where you're all looking out for each other. Playing through Borderlands with 3 friends, for each person I knew exactly what kind of guns to look out for and they all knew exactly what I was looking for too. We had some great times comparing stats (sounds boring I know) then taking a hunting party out into the wilderness to test our our new arnaments.
I've already mentioned the hollow, painted-on character that the world in Borderlands has and how this is actually more enjoyable in co-op. You never feel like you're missing anything when you're fucking about, chatting and joking, because the story is basically non-existant. This just serves to make the game that much more sociable & smooth for co-op play.
I would say that's actually where the sequel falls slightly short of the original. By having so much more to give with story, character and humour, I constantly feel like I want my mates to shut up so I can soak it all in. This makes Borderlands 2 a less socially enabled game for me, though I can obviously just play through the content on my own first and then come back to it in co-op.
So yeah, lots of points there - I'd be interested to hear anybody elses take on it. Especially if there's anything there that you especially disagree with.
Edit:
Once you get passed the loot, the shooting mechanics are not great, many of the guns feel janky and look terrible. The quest system is pretty bad, especially the save mechanics which punish you for being interrupted mid-quest by real life (spawn you back at the fast travel point). If they gave you a quicksave option when playing offline it wouldn't be so bad.
The masses of mele "rusher" mobs in a ranged game is annoying as it was first time out, forcing you to backpedal / circle far too often. It's a cheap mechanic and not needed when the AI seems good enough to have pretty decent firefights.
In reply to this, I will admit that the shooting mechanics in the first game aren't really tight enough to compete with how polished a lot of modern FPSs are, but I really think the gunplay shines in the sequel, to the point that I enjoy it far more than the CoDs and Battlefields of this world.
As for the guns looking shit, I disagree. Though there really isn't enough variety in the first game with the weapon models or scopes etc. Again, hugely fixed in the sequel - so many original looking guns, so many different kinds of scopes! Bayonets!
I never had a problem with the quest mechanic, but I understand that if you're looking for a shooter, not an RPG then you're probably going to be disappointed, because that's what this game is - a loot RPG that happens to be a FPS.
