You'll want to get this while it's hot! Right now, Amazon.ca has the Batman: Arkham City Game of the Year Edition on sale for $19 -- down from an MSRP of $40 and a sweet deal for one of the best superhero video games of all time. This copy includes lots of downloadable content on top of the well reviewed game which means there's no reason to pick this up if you're a Batman fan or know someone on your gift giving list that is.
Arkham City received a very good reviews and continues the story from the original Arkham Asylum. If you haven't played the original, we'd definitely recommend picking that up as well if you can find it on sale.
The deal is live now but, as with all Amazon deals, are short in supply. Shipping is free on orders over $25.
