I don't know why you're all so spewing. Sure the FIRST TIME you play you'll get spammed with a few achievements but after a few games you will hardly get them ~ever~ and the only thing you will notice will be the player/MVP info and cinematic cams which tbh will just be points for fun vent banter "MAN IM ALWAYS THE MVP U GUYZEZ SUK!".
It's so typical of the source community to shoot the idea down and act like wankers on the valve forum. Get over it and enjoy the fact that the game might be interesting again for a few days.
