Activate Fallout 3 on Steam?

[Default09]

D2D is selling Fallout 3 for 25 bucks.

If I buy there, can I activate it on Steam?

GOTY version btw.

Unfortunately No.

There's a list of games with CD Keys that will activate with Steam here: https://support.steampowered.com/kb_article.php?ref=7480-wusf-3601
