I haven't played DoomRL, but I understood that the PC would then start in a location designed for the challenge, right? Like if you chose Eternium Man, you would start in a SMC with no up- or downstairs? It might be interesting to play a JADE version of the Weakest Link...

Laukku I don't like this. Challenges in ADOM were about applying different additional rules to normal game, and you propose making them stand-alone games.

Instead it would be better if game tracked them automatically, like in NH. Or you could choose one of them at start. Then if you break challenge rules, game ends, and you go to separate hiscore list.

I wasn't proposing, I was asking how they work in DoomRL. Also, many challenge games are about playing in a limited area. (Brimstone, Steel, Eternium and Iron men.)
