I've had the PS3 for one day, I already am in possession of the following:

Owned:
Last of Us
BEYOND: Two Souls
Batman Arkham Origins
Best of PSN, Vol 1

Borrowing:
Skyrim
Tron Evolution
LEGO Star Wars Complete
Bioshock
Arkham Asylum
God of War 3
Uncharted: Drakes Fortune

I asked my friend if his (7 year old) son had any games he wasn't playing he'd think I'd like, so that's what I'm borrowing.

I haven't played any of them and I'm already overwhelmed. Did get to set up my PSN ID, which thankfully is doubleofive since it wasn't taken.
