I don't think I've played any meta-driven games outside of Undertale, so that's really my only point of reference.

Personally, I didn't even find the meta stuff in Undertale all that compelling. I get that it was trying to make me feel like a bad person for my rpg-playing habits, but if the monsters are so nice, why are they all trying to kill me on sight? I think if there was some more grey area to its message, I would have taken it better.

Also, trying to get the bad end was a grueling, miserable experience. That's not how you make me feel bad for my actions. The evil run is supposed to be the easy one so that I can get hypnotised by the money and xp that I'm getting without taking a second to look at the corpses I'm leaving in my wake.

I thought the pacifist run of Undertale by itself was a strong game, and the psycho path was completely unnecessary and poorly-thoughtout.
