Read the title. This is what keeps a lot of games alive (not saying that AH is dying), but it also makes them a lot more popular. I know a lot of you will deny it, but sometimes, unrealistic and/or custom game play is more fun. Dedicated-servers would allow people to set up their own server, with their settings and rules. Mods would be cool, but not as cool as dedi-servers or community made content. Now, what I mean by community made content, is like custom planes (GAH! I hate waiting for HiTech to add new planes, people do it faster themselves. Just look at FSX!), custom CVs and other custom things. I'm not sure if this has been asked before, but I didn't find it in search.
I'm gonna get a helluva lot of negative feedback from you "superiors", aren't I?
