Since the sale has started I have only picked up Ultima 7, but am looking at picking 1-2 more RPGs or adventure games. I have the following from the catalog :
BG 1
BG 2
Torment
NWN
IWD
Ultima Underworld
Arx Fatalis
Might and Magic 1-6
Stonekeep
Gothic
Gothic 2
The Witcher 1
The Witcher 2
Arcanum
Divine Divinity (didn't like because of the starting dungeon)
Realms of Arkania 3 (didn't like because of the obtuse ruleset)
Fallout
Fallout 2
Nox
Ultima 7
The Longest Journey
Sanitarium
Dark Fall
Broken Sword 1

I'm open for pretty much any game in the genres but they need to have:
-An easily accessible detailed minimap or some way to tell location if applicable. I can't count the number of open world games I quit because of a bad map or one that I couldn't find easily (Realms of Arkania 3..). Blame the terrible sense of direction.
-Simple puzzles. I play these games for the story or world, not to slam my head against the wall trying to figure out some inane logic.
