Backing up a turn

[Aethaeryn]

Perhaps a RPG would be more in line with your desires.

Sadly, Wesnoth is probably a better RPG than most other FOSS RPGs I know of.

I mean, sure, Nethack and other roguelikes qualify as FOSS RPGs, but they all have permadeath, which bvanevery would very much dislike. Plus, after using Wesnoth's damage system, Nethack's damage system stops making sense ("How is a spear a good weapon against skeletons?").

And any GUI for Nethack looks painfully bad after using a game with Wesnoth's art standards.
