My god. COD kiddies already have their game, it's called COD. I wish developers would quit trying to emulate COD, they're not going to gain their audience. Activision will release a new COD rehash every single year and it'll sell a bazillion copies. Other games will have to succeed by NOT being COD.
In terms of console shooters, before COD became the mainstay, what was the big one? Halo. COD succeeded by being different. If something else is going to take over as the new blockbuster 10-million-selling shooter, it's going to have to buck the trend, not follow it, because following the COD model means you'll only ever be second best.
Counter-Strike is fine how it is. Valve is going to be making minor changes that will not unbalance the game. There is no need for regenerating health, kill streaks, iron sights, or BLOODY SCREEN SO REAL. Oh and iron sights already exist in the game, it's called "the crouch function." Has the same overall effect - lowers movement speed, increases accuracy.
If you like CS, you shouldn't want it to change too drastically. If you don't, then why even bother? Just stick with your casual baby console shooters like COD.
