Its a mod for GTA:SA that allows better multiplayer action than GTA online does.
Ive been playing it since around 2007 or 08. I like to roleplay as a homeless dude from Blueberry who goes around quoting Carl Marks at everyone. It’s pretty fun, and I’ve been doing it enough that im known around one particular server for doing it.GTA:SAMP isn’t really obscure, but at this point it’s old as fuck, and nobody really talking about it anymore.
