ive got the orange box, only had time to try out portal... but
ive gotten throu all of the 'testing levels' and a good bit after that, but everything so far has been so strait foward and simple its been boring.
actualy,this game has a problem i find allot of games have these days... they tried to hard to make sure everybody could play this game, removing any element of though or skill needed to play :/ ah well, maybe it will start to be a challange soon
Edit:
Just finished it... i give this a challange rating of 2 out of 10.
there was actualy one part i though was going to be a challange, but i was mistaken, as there was a 'portable' wall just behind this said section, even tho it would have been possible by other means that WOULD have made it a challange...
