AHAHHAHAHAHAHAHAHAHA
Holy stuff, nice.
EDIT:
Family RP, where the lonely hang out and pretend to be a mother, father, uncle, etc, much like babyfurs do with their so-called families (though without the incest yiff) just because they got disowned from their family IRL.
Jail RP is a team deathmatch-based minigame where guards must let prisoners out of their cells without letting them escape or get weapons. The minigame is popular with the 13-year-old boys on Blockland since it's the only game mode Blockland has involving violence.
City RP is where players have to get a job and build stuff to survive. That is all there is to it. Disregard the name too, because players will probably be busy deathmatching each other as usual.
