GT Legends is a 2005 SIMBIN title (known for their racing simulators). It's new on steam but the retail keys activate. There's a CAG thread here. However here's what I did.

Use a polish proxy. I used this webpage based one: http://iphider.pl/

Log into your account through the proxy. http://forum.cdaction.pl/index.php?a...&section=login

Then go to this page through the proxy (box in the upper part of the screen, a little below your url bar). http://www.cdaction.pl/seriale/GT_Legends

It will then inform you that the code has been sent to your email

Retrieve the key from your email and strip the - from the code so it looks like:
4P6F9E28NMNE6GQPKQ6JGCCA4925
and enter it into steam.

Worked for me. I'm a bit of a racing nut. I own all of SIMBIN's RACE07 DLC/derivative titles on steam (summer sale, ~$24). If you are expecting an arcade racer you will be sorely disappointed. You will race like you took your car to the track. For a racing nut, It's a nice addition.
