I've been trying the demo on and off since it came out..
+ the graphics are really good in 1080i. It looks so damn clean. Wow
+ the gameplay is pretty damn fun. The missions are fun and so far they don't feel too gimmicky unlike GTA:SA (i did laugh at the 'rescue hoes from their pimps' mission)
+ the shooting and aiming is really good. I like it. That mission where you have to clean out an abandonned shop was fun.
+ Great selection of gangsta music
+ The physics engine is so much fun!
+ the map system is great -- you actually pinpoint a place on the map and it will make you a path like on a gps system.
- the framerate can get pretty random, but nothing unplayable.
- Physics bugs can take you out of the game, but I assume they will be fixed in the final release
- What's with those disappearing cars? O_O
I think it's a pretty damn solid game. Certainly not a classic but a good B grade title title at least. I can't wait to try the multiplayer in the final version.
