Being a survival horror nut, I was totally looking forward to this game and picked it up day one. I loaded it up w/my HDD, and decided to give the online game a whirl. At first, I was pretty disappointed b/c the people I was playing with were complete retards. However, I picked the game up again last night and decided to play the one-player game. I LOVE IT!
You pretty much rule your other group members. If they have an item you want, just go to your menu and request it. If you need help, just yell. Its certainly not perfect, but it works well enough.
And I really dig the way the game is broken up into scenarios. You can just go nuts and use all your ammo and healing items and then you get to start fresh in the next scenario.
My only gripe is the way the scenarios tie together. The first one is basically surviving the outbreak, but the next one starts out in Umbrella's lab with no explanation as to how you got there. Plus I had different people with me! Heh, craziness.
Give it a chance, or at least get it when its cheaper so I'll have more competent people to play with online.
