Randomizers are a fantastic innovation of the past decade. They can breathe so much new life into a game you've gotten comfortable with, where subsequent playthroughs are becoming stale.
I played through a Dark Souls randomizer a few years ago and it really made me explore a lot more like I haven't really done since my first playthrough, since I eventually learned where to get all the equipment I like and which areas aren't worth going to.
I'm just glad we're getting to a point where they're at least a little more mainstream.
For quite awhile there, a lot of randomizers would include potential requirements like knowing how to do some arbitrary wrong warp, or some highly technical unintended interaction. They felt like toys only for the speedrunning community.
