War Thunder as well, I used the Eagles I had lying around from... the tutorials I think? Regardless I hadn't paid money yet and got a days premium then started the US air force from scratch (I'd only gone to rank 3 with the British previously using PS3 pad). I gotta say it was a lot of fun and way better on mouse and keyboard then it is on the PS3 controller to me, just lets you focus on playing the game and you get a better spectacle as well. I've opened myself up to 2 styles of play now though which was my main aim, either traditional dog fights with the Brits or boom and zoom with the US.
Other games GTA IV (PC) is taking alot of my time and picking up BF3 again (PC also).
