Finally got into a couple pvp matches today. Before I started playing Warface I was playing CoD Modern Warfare 2, and CoD still plays better than Warface. It's not totally bad but controls seem a little sluggish and graphics seem a little low rent. I expect more out of CryEngine but it is the beta, so hopefully they downgraded graphics a bit for that purpose.
@Monsta Mack: Funny you should mention Counterstrike because I was thinking the exact same thing when I was playing this afternoon.
As a free to play game, it's totally fine. If someone wanted an occasional FPS fix, this would probably be fine for that purpose. I wouldn't pay more than ~$10 if it was a pay game.
