if you think noctiumrp would pique your interests, it's pretty medium-paced and backtag friendly. apps are pretty simple requiring only one comment, and ac is very lax (5 network or 3 log comments with tdm replies counting as activity).

it's very much a mix of fantasy, sci-fi, exploration, and can be sol if you want to play that angle more! also it's sex-friendly so the option exists but isn't required to engage with if it isn't your slice of cake.
