Honestly if I was actually in this situation I have no idea what I would do. Sburb, clearly, fucking sucks to be in. But it has still been one of my biggest escapist fantasies whenever life sucks too. I don't think it would be worth it in the long run; basically restricting all social contact to the handful of people I am playing with for the rest of my life and knowing that I am forever separated from all people, all culture, all places, everything that I didn't bring with me and that I can't manage to alchemize. Just knowing that I could never watch a new movie in the theater or listen to a new song probably wouldn't make it worth it. But I still can't say for sure I wouldn't play. If I'm being realistic the most likely outcome is that I would just be paralyzed in inaction, inaction in this case obviously meaning I don't end up playing Sburb.
