For me, I prefer
Neither. Each of the two forks' pros and cons crosses each other out for me...
MG is good for multiplayer and some features that GAE doesn't have... and the megapack is a nice too. People could say that it's too big or it's quality can't be compared with magitech...but people can always download a version without the megapack. For quality, megapack is pretty good compared to most of the mods/factions that Glest has.
GAE, great features...but its lack of good multiplayer makes it kinda bad.
That's main con. People could say that the main con of MG would be that it doesn't have as much features or not enough features, but its multiplayer, other good features, and future features or other "stuff" makes it up for that. With the main con for GAE same thing...its great and many features basically make it up for that. But multiplayer is kinda bigger thing...part of the reason why MG has more downloads than GAE.
improved pathfinding
Well, MG has it too. I guess ya' didn't know.
Now, maybe even better than GAE...not sure.
