You could try the earlier Might & Magic series, though the graphics on the older ones are a bit dated. M&M 6 had by far the best dungeons but you do as much walking around maps as you do in BG. M&M 7 and 8 have improved graphics and i loved 'em all! You get to have a dragon on your team in M&M 8!
If you like soloing, try 'Thief' series
