I'm gonna take another crack at this.
I'm currently playing the IBM port of 1.1. Is there any particular reason to prefer another version over this one?
By the way, Squeeealer, if you want to get into other games in the genre, I recommend Brogue, Sil, and the original Shiren the Wanderer.
Brogue, as you probably know, is essentially a more refined and complex version of Rogue.
Sil has what I consider to be the best tactical combat in the genre, as well as a solid and unique character building system. It's based on JRR Tolkien's "The Silmarillion" and is very faithful to the source material.
Shiren the best consumable-based strategic gameplay I've ever seen. Very high frequency of dangerous enemies, but it gives you the tools you need to deal with them. Make sure to avoid the item warehouse, as it makes the game too easy. The SNES version is slightly preferable over the DS port, but both are good.
