For TDU2, there's a few tricks mentioned in the game's Steam forum to get it running well. But to get it to launch at all you actually just wait it out. Click yes to playing offline, then just wait about 60 seconds and that Play button will change from greyed-out to clickable. It tripped me up at first as well.

SUPERCRACIOUS MUCHACHO! Thanks for the crapload of games! When will I find the time?

Thank you for Helldorado!

Thanks for the Witcher man, been wanting to check it out but would have never bought it seeing how it's more expensive in Europe -.-

Thanks again.
