Did i get infamous 2 for free?

I went to download the Infamous 2 full game trial,but then i seen how long it took to download.Then i was just messing around and clicked on the full game,and it started downloading.Is it just a glitch,or is it the real thing.I really hope it is real bcuz today is my birthday. :P...if not,thats ok too,i will just buy it later.
