I played Batman:Arkham Asylum for about a minute on PS3 and wanted it again. Check Steam today and they're having a sweet Batman sale.
I got Batman: Arkham Asylum GOTY edition, Batman Arkham City GOTY edition, and Batman Arkham Origins for $4.99 each..!!
Get them while they're hot - if you haven't played them yet. I know they've been out forever but I never did so I feel like I robbed 'em !
I didn't like the last one, but the first two (especially the first one) are absolutely brilliant.
