I dunno. In theory, Second Life is the answer to all fetish problems. There isn’t a map or content that caters to your specific tastes? Make it yourself!
To put it politely, though… It does not play out like that. Granted, I only popped on for like a day a couple of years ago, but from what little I saw, I knew it was not what I needed.
User-made content was very hit-or-miss (mostly miss), and frankly, the idea of paying LindenLabs real money to allow your fetish dungeon to exist is just entirely unappealing. And I don’t know if they’ve improved the game since, but it absolutely chugged for me.
Altogether, it just seems entirely not worth it. Dedicating oneself to generating content for SL doesn’t seem particularly enriching when people can use that effort to make their own content for their own projects.
