Fy Pool Day: Still a classic (and played) to this very day. One of the most popular community made maps. Trade Plaza 2: Oh man, that map feels nostalgic now because I remember spending hours on it in sniper duels. Not to mention the first version of it (trade plaza 1) is pretty nice too. Awp Lego: I first played on that map in CSGO during the peak of the skin and gambling scene in 2015/2016. Said map was mostly hosted with !WS and !Knife commands which grants you access to all the skins in game for free.
I first saw AWP_Lego in a game on crazy games about minecraft characters shooting each other with paintball guns that looked like water balloons. I had no clue it even existed outside of that game. Anyways, if you can find the game, it should have MC paintball skins. I'm not saying it's the origin, but it may be a good start. Edit: Its called "Modern Blocky Paint"
Cool video. Also it's not too obnoxious, but listening to it with headphones, I think the background music's level could be lowered a bit, it's a bit distracting at times.
