You will play Fear&Hunger and feel true horror, you will play the lisa series and the masterfully fan made side stories and it'll change you forever . You will play off and find sense in it's nonsense.
You won't regret it. It's one of those games that I still think about even a year after playing it. It has some flaws, and as said isn't for everyone, but it is a top 10 game for me, and anyone with similar taste will probably appreciate it as well.
Personally it's more the story for me. Not only it deals with some heavy themes, it's such a constant descent of things getting worse and worse and worse, full of pretty much arbitrary misery, that at some point I just don't feel motivated to keep going.
For what is worth I can agree that calling it the Painful RPG is on point.
I can handle turn-based RPGs, even difficult ones. I do like OFF a whole lot. It's surreal setting and mysterious quest was much more compelling for me.
I totally understand. For lisa, The story is heavy, too heavy even. But it's something we usually shield ourselves from, something we read about on a news article, feel all kinds of emotions but just try to forget later. I think lisa engrain it in our minds and makes us be more understanding of the pain of these people.
Not OP, but for me, it was gameplay. I've tried multiple times to get into that game, but the gameplay just detracts so heavily from it (for me personally) that I haven't been able to get into or enjoy (if 'enjoy' is even the right word) the story.
There's no shame in cheating. While some people enjoy the hardcore gameplay it's not for everybody.
While i think the devs should always give the player an easy mode to enjoy the story and world, it's possible to cheat just enough to make the gameplay more bearable while not destroying the gameplay.
Warning: all of those games contain stuff that can fuck you up if you're not expecting them, so check trigger warnings as required. That said, I'd also add OMORI and Jimmy and the Pulsating Mass to the list - IMO they are much better than OFF as both games and stories while playing with similar themes.
