As a DCS hoarder, I certainly understand that it's possible to collect 'em all, but it's impossible to know 'em all. That's made me appreciate the growing stable of older aircraft for variety and try to focus only on a couple newer ones. I also think a big part of the fun is learning and practicing, whether it's the familiarity of hopping in the P-51 or Huey, or maintaining Hornet skills on the boat or in the air. Spending some time focusing on one aircraft, and then going out and utilizing the stuff you practiced in a campaign or on a server, is really satisfying. Doesn't even matter which aircraft.
