probably pony.town . i actively play it so its kinda a switcheroo. In the issue of users, socializing can be quite tough (i add into that as i suck at talking to people), there's quite a lot of drama among fandoms, and quite a few people can be nasty on 18+ server from what i remember (i got banned from 18+ lol),,, otherwise the game is fine, it's mostly a hangout game and socializing is the main aspect to it.

it's nice in design quality, but considering my 2981.8 hrs playtime (AND COUNTING) i can safely say that ponytown is the worst game ive played.

that and the sims 4. i got bored very fast.
