Orion! Hey, welcome back! It's been a while (6 months? Feels like a lot more).
Anyway, Daniel's indeed been inactive for a bit, though Silnarm and Hailstone do most of the GAE work. Recent changes to GAE are:
-More Lua
-New pathfinder
-Water Units
-Various bug fixes, etc
-Debug mode (allows lua commands)
As well, GAE 0.3 will be coming soon, within the month. It will boast a new GUI, even more lua, MegaGlest's particles (see below) and carrying units.
Also while you were away, Titi started a MegaGlest branch of glest, which has improved multiplayer with a master server as well as improved particles, such as always on particles (ie: smoke from a building).
