few if any bugs at all and very stable. If you have an interest in the air war you'll love it. About mods and other scenarios; there are some Art mods around, but I have no clue if there are any other scenarios floating around.
On of the bad things, is that the community is very small and if you're looking for an opponent, it might be hard.
If you're still really into the original, then you should buy it.
Personally, I think the game is worth 5 stars. If the price, 3 stars and the lack of additional mods hold you back, then you should still buy it.
If you're not really going to like it that much and thought the original was ho-hum, then you shouldn't buy it.
THERE WAS A FIREFIGHT!!!!
