It's nowhere near to mature. Lacking comms, not much of a single player campaign to speak of. Memory leak still crashes the game after a few hours. Sounds are hit and miss, hardly hear gunfire in the cockpit but I can hear enemies coming from behind. The doppler effect on the different plane engines has improved with the last update.
If you have a good machine it's playable as long as you're not to critical for above issues. Treat it as a paid beta and keep your fingers crossed it get's finnished to the old Il2 standards. Going back to Il2 is a bit of a bummer because Il2 Clod looks so much better and the detail is stunning. I love to just hop in and fly around for a while doing circuits or buzzing through hangars.
What this sim also needs is an Il2 style quick mission builder. Not that big of a deal right now but when the other theaters start arriving over time mananging all the different planes and maps becomes important. It's what kept me with il2 for 10 years. Quickly setting up a mission, picking nationalities and custom skins is not as intuitive as it could be. If you allready own the game and have a good system check it out. If one has an older setup I would wait for the feedback from the latest patch they're working on before I spend any money. Could be that the Battle for Moscow becomes the patch we're all waiting for.
