1. You don't want the medieval + magic world and want to explore other timelines. Maybe futuristic, Star Wars etc.
2. You don't like the mechanics. Maybe the game system complexity slows you down or else there is some weird arbitrage opportunity that messes up the incentives. (Let's spend the whole game killing orc babies to build up XP instead of solving the clues and then just beat up the bad guy at the end).
Do people have good recommendations for substitutes that solves #2?
