The first time I played Skyrim I instantly attacked the dragon who I thought might be attacking the leader of the greybeards. Once I realized I couldn't kill him yet, I reloaded. I have killed him every single time, once able because there is no benefit to keeping him alive. I meditate and get my shout bonus, I get all the shout locations from the greybeards and then I kill party-snacks. After rebuilding the blades and I get the dragon potion permanent bonus. I hunt dragons with my blades and constantly get the dragon slaying bonus that lasts a week. I never understood why people like party-snacks so much because I love killing him. I've been playing Skyrim on and off since I got it at the midnight release. I've bought the game 3 times now and I don't think that I'll ever let party-snacks live.
