What kind of shape is the newest version in? Is it at least kind of stable?
We're talking about Julian Mensch's Incursion, yes? The newest version is the exact one he released a couple years ago before he went into his big code refactoring hullabaloo prior to officially declaring the project dead.
Having played it for ages I'd personally call it 60% stable. The more grievous crashes don't show up untill you hit deeper depths, barring completely random cases. (Like crashing to desktop because you suddenly hear a spell on the other side of the dungeon)
This was my favorite roguelike, but being unstable, dead, and filled with feats/skills/prestige classes that are unimplemented has dampened my enthusiasm. That and, you know, crashing to desktop with 95% certainty on any action while being just at the final encounter.
I wish it was open source so someone could at least remove all the feats/skills/prestige classes that have a big fat
[UNIMPLEMENTED] on them in-game.
Ah who am I kidding, time to roll up another character.
