I started playing this on Saturday, and I'm now Ranked #8. Some of you might remember I only played the first game
recently, and I loved the hell out of it. So far, I'm enjoying NMH2 far less than the original, mostly due to the "improvements" made to the sequel.
Lack of Overworld: As crappy as it was, the Santa Destroy overworld gave you a sense of place. Actually
going somewhere gave battles more meaning, IMO, than simply picking the location of a dropdown. Simply having that spacial awareness of where you were in relation to your motel, or the UAA building, or that bridge across the river.
Lack of Upgrades: I guess Naomi spent too much time upgrading herself and not enough time upgrading weapon technology in the intervening time period. I bought the first two beam saber upgrades after the first two ranking matches (after only 20 minutes of playing minigames!) only to find that...those were the ONLY upgrades available to me for the duration of the entire game. No more upgrading the battery power, No more upgrading the damage...what gives? Now I have no more reason to visit Naomi ever again (aside from the obvious) and I'm not even 1/10 through the game.
Lack of Fair Combat: Multiple enemies attacking you at once sounds like a great improvement to the combat system on paper. Due to the poor camera and poor movement controls, combined with new enemies that are harder to stun and who attack from behind each other or off camera, it's just an exercise in frustration. Especially when getting shot by a machine gun, knocked down, and kicked repeatedly only to get shot and knocked down again just as you get up. It's not great. Gun Millionaire's exploding bouncing coin shot also falls in this category.
Lack of Pacing:The necessity of doing sidejobs and generi-assassination missions in NMH1 I felt gave the game a great rhythym. Do a new sidejob, do a new generi-assassination mission once or twice, run a gauntlet of foes, fight a cool boss. NMH2 just goes: Fight <10 guys in one room, Fight a "cool" boss. Again, on paper this sounds like the perfect way to improve a sequel, but to me it just makes it feel flat. How can you feel like a high is high if there's no lows to compare it to? The brevity of the pre-boss melees sees them end just as you're getting into a flow. There's no opportunity to just wail on loads of beam saber fodder for any extended period of time. Then you get to the bosses and they're simultaneously more frustrating yet still easier than the bosses of the first game.
So, that's how I feel at least so far. I suppose this all sounds much more negative than I really feel about the game. I still like it a fair bit. I just feel that its not as special or as great the second time around due to the improvements/compromises made in the sequel.
