Since the NDA lifted today I thought I'd comment on this. I've been in the closed beta since June and I have to say that the game is really fun and coming along well. It's a beta so there are some balance issues but I think they are on the right track. Being a cryengine 3 game it doesn't take a high spec system. Also the F2P aspect doesn't seem like it will be pay to win. Paying just seems to take out a lot of the grind earning money to buy/upgrade mechs.
