You can get Blur at Gamestop for 10 Euro now but you have to trade in a game worth 15 Euro. ie. a recent game. Unfortunately they won’t accept multiple older games, and the games you’re trading in have to be the same format as the one you’re buying.
Borderlands is new enough to be traded in for it.
Oh, I played a brief game of Blur this morning and in the full game my stats had returned to rank 1. Still, I came 6/8 and I was 4/8 for most of the race 🙂
