Valve have been talking about it for a month now and we now have the beta version. I liked the idea at the started but now I thinking 'what is the point'. Steam needs some open and closed areas. The beta just feels abit empty right now.
Things are 100% great or useless. My favourite thing is that it has most town in (my hometown is there and that is saying something). The worst thing is the stats, they are weak.
Overall I think it could be alot better but its only a beta (why call it a beta when the whole thing is going to be free inthe end).
This beta is the best one yet. The clickandbuy beta was rubbish.
BTW everyone buy the iD super pack
