Here's a question for you: Given that the fantasy genre has certain assumptions about "normal" fantasy, how "weird" do you like your games?
Depends on which assumptions you talk about. I like to mess with races -- I'd rather have half-giants and cat-men than elves and orcs -- but I don't like having spellcasters in every town and hovel. Magic isn't science, and even in high fantasy I think it should be unpredictable and unreliable. My favorite campaign ever revolved around national politics, had weird races, featured no spellcasters of any kind, and only two magic swords showed up. But the players got regular (if cryptic) counseling from the ram-headed demigod living in the swamp nearby.
Now I'm meandering. Anyway, the key thing for me is consistency. I like a setting that has all kinds of crazy stuff happening, but it all has to make sense when you put it together. DragonMech is very cool because it adds one big weird thing (and lots of neat little weird things -- slathem and tortogs and clockwork familiars...). But the mechs, unusual as they are, have a place in the setting. They exist for a reason. Weirdness annoys me when it's just there for its own sake.
