"There's always room for jello. So says DOOM!"
Wizardry 6 & 7, if you can get them to work on your comp. Both are old DOS games. Use DOSBox, but that guarentees nothing, as Wiz7 refuses to work for me even then. Devil Whiskey is highly similar to the old Bard's Tale games (but don't try to write down all the text while in the dungeons). Fairly decent, and has many, many mods coming for it, including a BT mod(already out) Bard's Lore, another, and Wizardry 1. www.devilwhiskey.com
Early Might and Magics, up to World of Xeen, but like Wiz6-7, they are old, hard to find, and only work in DOS. Xeen has a few issues with DOSBox, nothing serious, but it is irritating to play. MMIII I haven't got set up properly, as it runs almost as fast as a 340 Duster.
