This game is a true gem. I scooped this one up fast!
I am so glad an Indie developer took on classic strategy space wargaming. I still have a copy of "Star General" by SSI (made in 1996 mind you) on my pc. If you are not familiar with the game, try it, and you'll know why I fell in love with Supernova 2 so quickly.
I've no suggestions at the moment, but I do look forward to continued play with this title. I did not get much out of the first game, but S2... nice work Winter Wolves!
