Yeah, I could use different systems. I'm making my own system which is far less combat centered. I can deal with the combat, but what I don't want to deal with are my players, honestly.
I've has about three different groups so far in my DMing time. All of them had the same thing in common: they loved killing things. It wasn't just, "let kill the monsters and take the loot." It really became killing just to kill things.
Maybe I'm just a little crazy. I've considered this many times. And i know the game isn't real, but I still don't like having the things that I create be brutally murdered just because, even if they are imaginary, and i do make the NPC's of my world...and all the other stuff.
One time, it was an NPC i had a story for. He had a wife and a daughter, who was key to the story i had in mind. Players go in and I, speaking as the innkeeper, say something that pisses off the player. So he cuts his head off, mounts it on a stick and parades around town scaring everyone off. The rest of the player thought it was funny. I was very sad. I rather liked that innkeeper...
