Played some of those way back in the day! I remember Purple, it was alright, very cute but quite frustrating.
Was a huge fan of Tales of Maj'Eyal 4 in like 2011, when it was still in beta and before they dropped the number. I was impressed by it because you were on a huge epic adventure, rather than just wandering off to go die in a hole which is what a lot of old-school roguelikes are like. I played a human berserker :3
After a while, I didn't like some change they made and swapped over to its main competitor at the time, Dungeon Crawl Stone Soup, which is also freeware. I still play an old version of that from time to time. I played a draconian summoner in that one.
