I'd still love a fantasy setting. You know, let my true sELF out. Get it? See what I did there? Don't acknowledge that, that was terrible.
A Victorian setting might also be fun. I'm curious what a cowboy setting might look like, but I feel like that could turn into a real nightmare. Probably the same with a Gothic setting, though the idea is fun.
I just really would have fun with a less than serious roleplay. They had us do one once, and I liked that you got points if you played along, but there weren't any real consequences if you didn't, for the most part. I didn't hate that.
