Don't even get me started.
I've spent a huge amount of time playing online games since broadband internet became available in my area (roughly 5 years). In that time, I've never played a game aside from Halo where I can beat a team really badly and still get a message afterwards saying "good game" from a person on the other team. In this game, the top player on the opposing team knew I hadn't died yet and tried for about 6 minutes to kill me, unsuccessfully. After the game was over, he sent me a message telling me how fun that game was with total sincerity. With my normal d-baggery aside, I love that. As with every game, you still get people sending you hate messages after games like that, but I've also sent and received tons of messages like the one I got yesterday. That never happens in other online games I play.
