I'm not trying to force you to play this game; I'm just pointing out logical fallacies in your argument so you can further cement your own argument.
There's no written rule in RPG's to kill things; the game doesn't force you to not kill anybody. It simply tries to point our that your actions have consequences that you can't escape from. This game has multiple playthroughs based on HOW you play the game and you aren't forced into any single one. You're basing all of this on things you've seen or heard; like your comment about the 25 hp thing. This game isn't one hit and your fucked like some games, it's far from it. You're supposed to die. You're supposed to come back, more determined than before to learn the patterns and win. Do you know how many times I died to some bosses? I believe I died so many times on one particular boss that the game text itself changed to say I'd been killed more times than I can count.
There's no rules for RPG's to follow; this game points that out and deviates, raising an eyebrow at the traditional RPG method of grinding until your ten levels higher and steamrolling. I still believe that this is the type of game you need to play and experience to enjoy. The whole main stream thing is to be expected of a good game. Of course people will flock to it. People flock to things they enjoy and share it with people. I'm not saying "your wrong" or that your opinion is invalid or that you absolutely, 100% need to play this game, but I don't understand why you just browsed into a thread about a game you don't play and post that you're never going to play it.
To me, that says you either want to be convinced TO play it, aren't confident in your own reasoning or just trying to start shit to put it very bluntly. Also, you stated you refused to play because of Sans' grammar, but the very next post your telling me you refuse to play because of the Tumblr fandom and you just don't want to. Both reasons are (one far more than the other) reasonable, so I'm just not really sure what it is.
