I hear it's good w/ a joystick, thought given the engine don't think it's really that improved over M:KB. Beta (closed) was ok because of massive xp boosts. But play for a few weeks and it gets to be the very grindy even w/ boost. (And can't imagine it on release, I already hate world of tanks because of how extreme getting to t7+ is without premium though I'm a masochist and still play.) To me, after a while the matches become all the same. I liked low tiers because you were more apt to get really fun engagements where your at 10% health and fight off 2-3 noobs.
So far, War Thunder if you are into the planes is a massively better choice. World of tanks model works well, but for airplanes, it just feels too like a wii game or something. Maybe they'll fix it up more (I'll try it again in a month), maybe make bombers worth a shit like they are in thunder. (Nothing like losing after downing fighers 3:1 but no one went after the bombers who are pummeling base and they are so high that you can do nothing as it would take several minutes to climb high enough.)
