You play Aces High. That is the most arcade ish game right under War Thunder and you know it.
Come play in Enigmas Cold War server. You'll find action faster than any other game and any other server.
IMO
1) DCS seems to be a money pit, which can exclude many would-be players.
2) DCS FM seems to have issues, according to many players, and many admit AH FM is closer to reality.
3) Many who fly here have been doing so for 20+years. They have a history with AH. It's like breaking up a 20+ yr marriage.
4) I've seem comments that one can fly for a hour and not see a plane, and visibility isn't great.
5) DCS is more of a sim, AH is sim played as a game. The sacrifice of some graphics is what allows large numbers playing.
6) AH is just more fun
THAT SAID, to each their own. I think they each draw different crowds.
One relies more on graphics
One relies more on game play.
