I haven't bought a Sturmovik game since Pacific Fighters and really haven't played anything in a long time.

Just wondering, if I wanted to catch up, what new games are there? And are they able to be installed into one game, like how pacific fighters, forgotten battles and the aces expansion were?

I googled and only found something about a PE-2 add-on and Manchuria add-on (which I have no idea what they actually are), cliffs of dover (is that game really as bad as people say it is?) and stuff about Storm of War: Battle of Britain. Is there anything else to get the full range?
