I agree but you missed 2 things that I would add:
1) I miss having EVERY terrorist loaded from the start of the level (I hate how guys spawn in areas that you already cleared in the Vegas games)
2) Full-time FPS/ no cover system

I think Raven Shield is the best Rainbow Six game of all time. If they took that same game, updated the graphics, added the gear customization features of the newer games, and then re-sold it, I would buy it. An AI upgrade is overdue as well, but I'd still buy it without.

I know, Counterstrike hasn't been hacker-free either but i'm really hoping that steam will provide a more thorough anti-cheat system. Is there any information on this? I liked Combat Arms when it first came out but when there are adds for buying hacks right on the game's website, you know you're in for some frustration. After being insta-knifed or having my ctf match ended by some idiot with a teleport hack for the 100th or so time, I finally gave up on it. If it's fixed, I'll try it out again. Though, it'll really need to impress me in order to steal my time from Blacklight and it's superior graphics.
