FFS I paid full price
Felt a bit sad at the end, not sure it was really worth £30
I found Portal a bit dull, I'm not sure I should bother with the second.
My only criticism is the lack of updates, as the devs said they were planning to add in a lot after release for free, such as co-op challenges.
It's been 2 months since launch and they said they were coming for free in the summer
Not sure how anyone can complain about Valve's updates.
