Obviously, I'm not going to give up hope on the game based off 4 beta plays where for the most part I was confused (went 3-1 the one loss with terran) but off the bat I found it to have higher latency (even with mouse movement), harder to keep track of your units, and less fun. When I first played SC1 back in the day I remember really enjoying the units and feel of the game right away. Maybe I just need more time to play SC2 O_O. I was probably expecting SC1 too much.
One big big big complaint I have about the game is the unit sounds. They all sound super weak and wimpy. The hydralisk attack sound? Lame. The hydralisk death sound? Lame! Tank going into siege mode? You can barely hear it. What's up with that? All the units have less feel and the lack of defining sounds actually kind of throws me off O_O.
Clarity in the game felt really hard also.
Anyways, sorry to be negative, hopefully I get to play more and I end up liking it.
