Crimson Skies was my first entry to multiplayer.
It took me awhile but I found a sight to download the game, any patches and you won't need the disc to play. Site forums said it will work on Win7 and 8, not sure for Win10.
CSexe
been playing for couple hours now, oh what fun!
tried to download it with out success.
I had no problems with the download from the above site.
The only issue I have is it won't save my plane and campaign progress.
Just a heads-up my AV flagged it as a Trojan: this maybe b/c of how it operates (file downloader) but after getting hit by a crypto locker variant from a drive by site im a little cautious
I think it was flagged because it has code so you don't need the disc installed to play.
Played it a long time ago. Was fun, loads of different custom planes to try out.
