Just finished the game and it seems to me that Obsidian went with the "more is better" philosophy: More upgrades, more weapons, more powers, bigger stats, higher levels, etc. Not a bad idea, but not enough. The game is a munchkin's wet dream, but all the items get a bit annoying and the random drops are just lame. Some stuff should be random, but this is way too much.
The influence system is a good concept, and works well early in the game, but later on there are hardly any methods to boost it, and the whhole thing drops out of sight.
The game is too damn easy. Except for a few solo NPC parts and some early battles, the rest is a cakwalk (cast speed, cast stasis, slash&maim, repeat in the next room)
Bugs, bugs, bugs. Most are conversation related. For instance, Visas had tons of options in my first conversation with her, but I needed more influence to unlock them. Later, when I talked to her again, those options weren't there anymore....
Also, characters not recognising your progress (this could also be due to bad/sloppy scripting)
Other bugs are with the interface. Game often ignores my input (I queue my main character's actions so the game can ignore them ond override them with an "attack" command). Not to mention the abysmal combat AI....
The story was good, up until the Jedi meeting on Dantooine. All those Jedi were glad to see you, they happily taught you all their special saber moves, and then suddenly decide to kill you. And to make matters worse, Kreia waltzes in and kills them with one force lightning.... From there on, the game goes down the poop chute.
Most NPCs were well concieved, but lacked development (except for Kreia and Handmaiden). In KOTOR1 this was achieved by individual character side quests. Here, you have to scrap together bits of info.
The game runs slower than KOTOR1 (which had a poorly optimised engine as it was), and I was honestly suprised at this. Obsidian did a big step backwards.
To sum it up, the game has great concepts and ideas, but more holes than a wheel of swiss cheese. It's a bit like your average political campaign: starts out promising, works great in the start, but fails to follow through. Obsidian has a lot more to learn, but at least they show some talent...
