I recently read this
Clock Tower 3 LP, made by the same guy that did the Resident Evil LPs, and it's view of a shitty game made me remember the best (and first) LP I ever read:
Limbo of the Lost. For those that don't know the name, LotL is a shitty, shitty adventure game that was under development for decades and is made almost entirely of shitty photoshops and elements (maps, backgrounds, item,s etc) stolen from other games (everything, from Diablo to Quake). The creators also tried to advertise it by sending "review copies" to some adventure game sites and then posing as random players that loved the game (in short, they were spammers).
Also, it makes no fucking sense. It's really completely fucking crazy. Be warned though, it's a thread on some random foruma not in Archive so you'll have to scroll through some comments to get to the next update. But it's worth it.
