Finished the DC. Game has aged remarkably well in gameplay. Still a better Metal Gear stealth game than Metal Gear Solid 4. Great level design. Decent story (even if it falls apart at the end). Yet another reminder that these kinds of games are disappointingly few and far between.
Integrating the DLC into the main quest works well and makes it the definitive version, and I like most of the boss tactic additions, even if the total sum of parts does skewer the difficulty towards the easy side. The pre-order DLC weapons integrated as general loot is good on paper, but the auto-unlock devices are still overpowered as fuck. The abundance of praxis points you'll have earned by the end is probably greater than standard Human Revolution too, so you're again left with almost everything unlock (literally). This was a problem with the base game though. Hopefully Deus Ex 4 is stricter in its praxis handouts.
The boss amendments are fine in the sense that they were awful to begin with so any extra option is beneficial, even if these extra options are mostly the same thing: hack a door to enter a new area, maybe crawl through a vent, disable or walk through lasers, activate turrets/robots to kill boss. The layouts change but the concept is the same every time, and if you don't have specific tiers of skill you're still gonna have to take them head on (though ammo distribution is more liberal in the boss encounters too). Namir was probably the only one that seemed a bit busted, because on the highest difficulty he's so agile and takes so much damage that, coupled with his explosive attacks, it's easy for him to take out your mechs, regressing the boss fight to the original idea (the laser rifle helps).
I played through on Give Me Deus Ex difficulty and rolled stealth/hacker/pacifists like I did on my very first playthrough, and had an easier time that, which was on a lower difficulty. Once you've got some good augs and equipment the game is really super easy to cheese. Cloak/batteries/stungun = win.
The game does have some production issues, like with animations, but a lot of those are due to the engine and restrictions the team had making the game. I ended up really liking the new lighting engine. I wasn't a big hater on the old filters, but the new lighting is really nice. Hengsha maybe loses a little something without the old lighting model, but that's about it.
Commentary was outstanding (played through with it on). Candid, honest, and thorough. Implementation could have been a lot better, like seeing the nodes instead of having to hunt them, and some cue informing you've listened to one already. But the content makes up for the execution.
No touch stuff on my end, played on PC. Touch stuff seems great from what I've seen/heard, but DX:HR already worked amazingly with mouse/keyboard (thanks Nixxes) so I'm not missing those extras. Don't need a guide or anything.
All in all, the game is still one of my favourites of the generation, even if the crappy stuff is pretty crappy. The final level is still total, utter balls. Fine idea, terrible execution. But everything leading up to it is amazing, and the commentary helps you appreciate the issues they had throughout the entire production. The Missing Link and the Tracer Tong quest integrated into the main game works really well. The latter was always a throwaway mission you can breeze through in a couple of minute, but The Missing Link is really fantastic and helps buff the lore and narrative in some important areas. Pre-order equipment integrated works, even if it does make the game easier. Praxis distribution is still too liberal. Some augs are borderline useless. But that's Human Revolution as it always was.
Very, very happy with the $5 I payed to upgrade, and I still think the game is worth the full price of investment if you've never played it before. Definitive version.
