If Undertale left you wanting more, this is where you narrow it down. Was it the puzzle or the adventure that hooked you? There is a list of just that. And if you play on PC, Nintendo Switch, PlayStation, Xbox and Mobile, filter by platform and skip the games you could not play anyway.
Sometimes what you want is not a Undertale look-alike but simply the best Tactical RPGs there are. That is what these rankings are for: no comparison to anything, just the highest-rated games. And if you feel like widening the net, the RPG Games ranking is a good way to run into something you were not expecting.
