Sacred Haven of Debauchery

That's exactly what I mean – I want to play games based on one theme, but not another. You like listening to electronic soundtracks for anime, but you don't like death metal, and I like playing mafia-style games set in fantasy worlds (this is just an example), but I don't like games set in sci-fi or, even more so, in real life (the "Hosovskaya psychomafia" game I played recently is an exception, because I really liked the description in four sentences and the simple, stupid setting that's about nothing, almost classic. There's no theme there at all).
