Noticing this more and more lately, but why do people keep playing a game once they hit that point where all they do is bitch about it?
Per my rant in another thread this has been most prevalent in my MW2 time. Some of the people I play with will bitch from the second the game starts and still keep playing for 4-6 hours with non-stop whining about how much everything sucks. If it really sucks that much, STOP FUCKING PLAYING.

This also happens a lot in single player games where I'll see people dreading firing up a game because they are stuck at a certain part. There will be much cussing and they might spend hours doing the same thing again and again and simply not having fun at all. I play games to have fun so I just don't understand the push to suffer through what should be a good time. If I'm not having fun, I'll try to play something else.
Time should be valuable enough to not waste it on entertainment that isn't fun. If it sucks to do it, it is a chore and games shouldn't be chores.
