I finally deleted all of my IL2 files, over 30 gigs. I have flown P51 sims since Aces Over Europe, Air Warrior, Fighter Duel, WarBirds and finally IL2. Each sim brought something new to the table and man...DCS really takes the P51 to the next level; not just cockpit management but the mass of the plane as well. Like playing chess with cheap plastic pieces, then you finally get to play with a set of heavy wooden pieces. It just feels right.
