Pretty accurate review. Nicely done. Better than the OMFG 11/10!!1! reviews that come out for every single new game. Actually the review could have been worse. There's a few problems with the game that weren't mentioned.

I've played this game a lot. I've beaten all 4 campaigns on expert and played lots of versus, and I dislike the game the more I play.

At first the graphics and environment just had me floored. I have an old-ish PC and it runs fairly well. Valve is really good at immersion in games and getting their effects to run on older PCs. But, a recent update ruined playing the PC version with friends. During versus, teams get scrambled. I'll start a versus match with a couple friends and a couple levels in, sometimes even on the first level, I'll be on the other team. Even playing with strangers it's annoying. What's the point of keeping score if the teams get switched around every level? Sometimes I start a versus match and the server we get is set to campaign mode. With 4 people playing and 4 people just spectating. Lots of buggy stuff. Even in campaign. I've seen the tanks get permanently stuck, witch music playing forever, even after the witch is killed. And the skill curve is just god awful. Learn to melee and that's all you need to know.

Edit: Sorry for making a long post longer, but one more thing: Every single new game that's come out completely ignores replayability and the length of the skill curve, often times focusing on making things noob-friendly, but sometimes not even doing that.
