I'm glad the overland map is back. I thought it gave the earlier games a sense of scale that the later games lacked.
Uncertain about whether I'll buy it though. On one hand Avernum 1 is still pretty fresh in my mind; on the other hand there is the "existing Avernum owner" discount. Hmmm…
Later edit:
Any new material?
Plenty. A new, large town with a pile of quests. New hidden dungeons. New hidden characters with lots of backstory and things you can do for them. A completely new starter dungeon/tutorial.
Okay, assuming a discount, it's a likely purchase.
