http://www.gaijinent.com/ Gaijin is a Japanese company that has been producing MMO games for a number years now. Their latest and greatest offering is 'War Thunder'. OK, it's definitely a poor choice of names, probably translated from a cool sounding Japanese name! Anyway, currently it's a WWII warplane sim, but they have plans to expand into tanks etc at some stage. They already have AI tanks as targets for the planes. The game has multiple battle modes, more than WOWP, and is a lot cheaper to play. Worth taking a look at!
