Get ready for more hats.

A game is not only graphics, when will people realize this?
If you play a multiplayer game it's normal you will have to install updates. There is no way to play without the latest version. Either find a way to upgrade your Internet connection or play a different game.

To OP - 'not like it has real maps'? This update has only 3 new maps, new video, and a few more nice things besides, but yeah, feel free to complain more seeing you didn't even bothered to spend 5 seconds to change updating options in Steam :<

No new hats? Wow, Valve is such a sellout; they ruined the core game to appeal to a wider audience!

Every few days? I think that's a bit of an exaggeration...

i bet its just like with dota, all u need is HATS etc, with dota is simmilar but well hat updates afrent that big except one 63mb update before ti3...
