I tried Undertale because of the good buzz it was getting, but it actively turned me off. I guess I was expecting something kinda relaxing to play when not in the mood for something requiring a lot of focus, so the twitch-based combat really drove me off, especially when combined with the lack of much tutorial. But I've never been a huge fan of JRPGs. (I still enjoy Chrono Trigger whenever I've revisited it, but it notably omits random encounters, which I can't stand.)
