I am definitely getting it! The first one was so awesome, like how it started off as clever puzzle trials, then developed into a full-on story and escape for freedom. I may have to buy The Orange Box again, since my brother traded it in to the shops, along with the best game of last year, Mass Effect 2 .
I've read that this one will be four times the length of Portal's campaign. It's no surprise, since it is a standalone title. I will get it on Xbox 360, since I am planning to buy a new one a few days before Portal 2's release. I cannot wait!
