There were a handful of gripes I had when I first say the gameplay footage:
1. The Crosshair - That thing looks awful. They better at least have selectable crosshairs like they do in other games, or just set it back to the classic one.
2. Models - Some of the models were really poorly done, especially for the nades. I remember one clip in particular where it shows the player running into the tunnel in Dust with a grenade of some sort out, and the thing looked absolutely terrible. They better improve on a handful of the weapon models across the board.
3. Map Changes - There were a lot of changes shown, some were good, others were questionable. The dust changes themselves aren't bad, but moving the bombsite entirely is a bit strange. I think Valve is trying to make every map balanced, but the problem is, for competative play, they don't NEED to be balanced. Look at mapes like de_train and to a lessar extent de_nuke. They are obviously CT-sided, but that doesn't mean it's unplayable, it just means that in a standard match T-Side is the real test. It forces teams to scratch and claw for those hard earned rounds, which is something that sets CS apart from CoD-esque games which are mostly about getting the most kills.
4. Molotov Radius - I noticed a particular clip on Aztec that was puzzling. The T's were rushing the bridge, and threw 2 Molotov's across the bridge at an AWPer. Now when they landed they spread out, but where the problem is, is that one of them started creeping OVER the box the CT was standing behind. That is confusing as hell to me lol. It also seemed like those 2 Molotov's covered at least half of that room which is a bit much.
5. Registry - There seemed to be some really weak hit detection even by CS standards. There were several clips where people would waste 3/4 of their clip on a target that was either not moving or they were dead on. I know CS isn't filled with Rail Guns, but the Rifles are fairly accurate when used correctly, and the clips I saw almost made it seem like they were either doing little to no damage, or the shots just were going all over the place\not hitting for some odd reason.
The graphics look fine, but I am just worried about some of the mechanics of the game. Also, I noticed someone asking why the game had not adapted "Iron Sights". Valve has said they want Counter-Strike to stay very traditional, and part of that is keeping Iron Sights out of the game. Otherwise it just becomes another CoD clone. Counter-Strike isn't about realism, it's about superior gameplay. I'd rather they spent years working on the game mechanics than adding extra features to the game that just cause issues.
