As part of Xbox's somewhat newly revealed Games with Gold program, Assassin's Creed II is now available to download for free for Xbox Live Gold subscribers through the end of July. Sure, it's a four-year-old game. Yeah, most people are kind of burned out on Assassin's Creed. But hey, there's no harm giving it a download in case you ever feel like visiting your ol' pal Ezio again.
On the off-chance that you haven't played Assassin's Creed II, this is definitely worth having a go at. That's probably not a whole lot of people though, because anyone that wanted to play this already has. For what it's worth, ACII is by far my favorite in the series, and I can't recommend it highly enough.
