For me as a modder, GAE has more features, so it gives me more options on how to make a faction unique. The particle aura thing titi is working on is the first thing which will really make me want to consider making a MegaG-only Dark Magic. The best possibility for me would be that titi could somehow put the code for the particle aura in GAE. Otherwise, I don't see a future in Mega-G.
Also, I don't like some of the features in GAE. I should really make a new topic about it, but there are some real inconveniences for faction testing.
And finally, coders, don't be fooled! Modders like myself are probably the most vocal group, but we are not the main users of Glest I think. The main users mostly want stability and eye candy over features and options I think.
//EDIT:
I made a topic a while back in General about features we wanted in Glest (that is, any and every version). It was an extensive list, so I wanted it stickied (which never happened). Now I have to search through a sea of old topics to find it...
//EDIT:
Maybe it could be moved to announcements? There it would be ensured survival, productivity, and people would see it. The Announcements forum is generally never used anyways, and has mostly old stuff. Actually, the MegaGlest topic would be better there, since it is not really a mod in the normal sense (here), and then less stickies would be on mods! Yay!
