I'm really into vaguely- or extremely-Earthbound-like games. Since Omori was already mentioned (and it's the best of that subgenre along with grandpa OFF and Undertale), I'll mention the Endless Empty, which is a giant CW for suicide and drug abuse, and also admittedly kind of buggy. Also I don't see it currently on sale despite it mechanically being very much a conventional RPG, so I guess that defeats the point of the comment, but it might go on sale on a later day! On a related note, Nepenthe (which is like if Undertale was written by Toby Fox's dad), is also not on sale.

Let's see . . . there's LISA and its offshoots, with basically every content warning short of snuff being applicable to those, and also it's full price right now . . . West of Loathing is cool and I assume the sequel is too, and those are actually on sale. Suits: Absolute Power is pretty good and also on sale. In Stars and Time is on sale and I really recommend playing the demo first because a) it is a better game and b) it doesn't have the same impact if you know what you learn in the full game. Neither Hylics 1 or 2 are currently on sale, which is unfortunate, because those are up there.

Moonring is free but also more of a CRPG I guess and also not Earthbound-like (which, to be clear, all the previous games are). Virgo and the Zodiac isn't substantially Earthbound-like but it's a good rpg on sale. "Get in the Car, Loser!" could only be more of a Hexbear sim if it was a) actually Bolshevik or b) framed around a trainride instead of a roadtrip, but as-is you're still a gang of transbians/cisbians fighting industrial demons and doing dumb quips, and it's also not on sale yet (I got it when it was free).

Uh, Franzen and Grimm's Hollow are both pretty good and they are free last I checked.

I don't know, I think this mostly wasn't very helpful, I just like RPGs.

I haven't played Cesspool but it seems neat and it's at a large discount
