If you and your friends can enjoy Diplomacy, that's great! But I do get tired of all the people insinuating that there's something wrong with me I don't like it.
There are certain personality types that tend to lead to negative experiences in gaming, though, and being a poor sport is one of those, and I do try to avoid gaming with those people when I can.
I still stand by my statement. It's just a game. Just because it took a few extra hours than most doesn't mean it should permanently damage friendships. Maybe take a week or two break from everyone to decompress from the absolutely intense and crazy experience, but not permanently damage a friendship. That's the sign of a very weak friendship, I feel.
As for more at stake...what's at stake? A 'yay, I won!'? It's not a poker tournament where the winner is going to take home $100,000+.
I should point out I separate games from gambling, because money does changes things quite a bit.
It’s the weak friendships that I’m concerned about damaging.
