Seriously. If you enjoyed the X series and like roguelites in any form, 30XX (and 20XX, the first game in the series) are easily worth picking up. And even if you only like one of those things, I’d say give 'em a shot because I can’t think of many games I’ve played that feel as good when you really get rolling.
True Pacifist Undertale just the other day. Which, to be fair, took me something like two years to get around to doing because I was way too lazy to deal with some of the ending fights of Neutral route.
Now I have the itch to go back and play EarthBound again… Which may be related to the lo-fi Mother 2 mix that got posted earlier today over in the Music community.
