WoT is essentially a first person shooter with tank skins instead of whatever else. I played it in Beta up until the big wipe, and didn't feel like grinding again to get all my top tier (at the time) tanks back. It's a "first person shooter" skill game, not a simulation skill game. The knowledge and ability required to be good at it doesn't really compare between the two games, both in spite and because of the differential in numbers of players. Claiming WoT is a superior game due to numbers doesn't really fly (get it) IMO, as most of the "great" WoT players would be either incapable or unwilling to learn a more difficult game, like the air to air component of AH2. Having played both that's my observation at least.
It'd be nice to have Belial back on the BBS though, for nothing else, for some more Tom Cruise like motorcycle posed pictures that the photoshop people can modify.
