Hmm, I think I finished glest - after a long and bloody battle, I won the "Mountains" map (my favourite one, followed by Ruins), against 3 Ultras (all 4 parties Magic, the 3 enemies in one team)!
Several maps leave no chance against a single Ultra I think (center punch beeing an obvious example, but also Island Siege 1 and 2). The default starting point in the Mountains map has the advantage that it can be reasonable well defended with Trolls (you need about 5 though) and Battle Mages.
Is there any challange left I could face? Otherwise I just have to wait for the next release/update
Kudos to the Glest developers, and to the Map creators!! I played the game daily for about two weeks, and enjoyed it immensily. Also, I played it on Linux Laptop (with a Mobile FireGL-2), and it worked flawlessly (well, 3 Ultras slowed it down from time to time...).
Cheers, Andre.
