There's a number of LPs on the Something Awful forums, I think there is even one that is active right now but if it still is I don't follow it.
Probably the classic example is
The Coldest War which is essentially 458 pages of random forumers with vastly different degrees of game knowledge screwing things up in hilarious fashion. Started in 2012 on a VB6 v5 version so very outdated (what's this nonsense about fixed engine sizes??
) but fun to read.
