Wat a qt
It was posted in threads I frequent, but I have an irrational hatred of leddit. It seems there are two versions of crawl that Linley worked on in there, so that's cool. I'm not going to download 7 gigs worth of games I'll never play though.
One notable game I also see in there is
poschengband, which everybody should play and which deserves a spot in the OP.
Poscheng is a variation on Angband with a metric shit ton of races and classes, and with a list of enemies that includes pretty much everything the dev has ever seen. Only in PCB can you be a Balrog, Quylthulg, mimic, or a
literal sentient ring of power waiting to be picked up and possess somebody, and fight Kenshiro, Santa Claus, the gods of the Olympus, Bill Gates, cyberdemons, the developer of the game, Gandalf, and Dio Brando.
I just did a count and there's 62 player races with differences beyond stats - such as androids only gaining levels from the equipment they wear, jellies absorbing corpses and gear to grow stronger, dragons and hounds evolving into greater creatures as they level up and demons needing to eat human flesh to survive.
