So; I threw down some ideas for a Dark Sun game (imho “D&D Mad Max with obsidian weapons and bug armor” is a neat idea). Noticing;
1) especially because the last really good Dark Sun info was 4e, this might be hard to sell players
2) especially given the importance of thematically cool combats in 4e, areas with cool gimmicks and usable features are the combat encounter equivalent to having cool NPC personalities in social encounters.
@Leucrotta Even with my dubiousness about 4e, I'd give it a shot.
@Jssra 4e is a pretty good system; I like 5e more than 3.5, 4 and Pathfinder, but would have to come up with house rules for a lot of Athasian stuff.
@Leucrotta Honestly? If "obsidian bug armor fantasy" had become the dominant paradigm instead of "elfy-dwarfy heroic musty-chainmail fantasy" I would probably be a much more avid roleplayer today. :)
