Panzer General 2, loved that game, downloaded tons of mods for it, played it in all sorts of configurations from the sophisticated to the silly. Then I bought Panzer Corps about two years ago and I haven't gone back to PG2 since, I thought about loading up PG2 and giving it a couple of rounds, but I don't think I would have as much fun with it now, so it just sits there.

Ive fired it up once since getting PC, sadly the graphics seem so poor now that I cant play it. However one thing it has that I wish PC had was defensive fire for artillery to any units in range, not just units artillery is right next to.
