Since I am about to hit 300 battles in World of Tanks I can now solidly say that I love the game.
If you like tanks at all (who doesnt) and like to blow shit up, this is a great game. The only caveat is that the game is brutal. I got to ask the developers about it at GDC Online and they just explain it this way: "Hey we are Russian, we have no problem getting killed over and over again in order to figure something out." I hope Americans dont puss out and get scared off when they get rolled starting out.
If you grab the game throw me a holler. I am Astrothumps in there.
