The graphics are nice, menus are slick, and the three classes are very distinct and balanced. There's no one obviously 'better' class, which is something I cannot say for just about every game out there. Overall, the game feels polished. The menus and game have been updated for added intuitiveness. Despite this, I just couldn't play it for long hours. There was just no 'hook' for me to get sucked in and want to learn all the strengths and weaknesses of all the units, etc.
The DRM with Blizzard games really don't bother me. The games have such a good community surrounding them that I think I may even prefer it. I can log in anywhere that has the game downloaded and play my account.
For less than $40, I think it is well worth a try. RTSs and this game in general has a very wide demographic. It is widely loved, so I think just about anyone can get some enjoyment out of it.
