That would've been my pick too. War Thunder is a lot of fun and has stunning visuals on highest settings, while it doesn't need a high end PC to play it at 30fps. I don't know how, but this is the only online game that has managed to keep me motivated for weeks. Sadly, a lot of people think that it's a rip-off of Wargaming's World Of Tanks & World Of Warplanes, but the guys from War Thunder started the development way earlier after they split up from Wargaming and became part of Gaijin Entertainment.
Yeah, and I don't care if it's a "rip-off", it's beautifl, fun, and true to the flight models of the aircraft. I used to play Air Warrior 1-3 on AOL and later Gamestorm a long time ago, and this is the first WWII flight sim since that is actually fun and holds my interest. Love it!
