Fez

People always hate on Microsoft for their Xbox Live Arcade rules, but Microsoft always has a pretty damned impressive XBLA line-up each year.

I think your missing one btw, there was a story about it on gamerzone 2 days back I think.

This?

There are many more awesome titles your missing like Minecraft, Fez, Retro City Rampage, Diabolical Pitch, Happy Wars, Haunt, Skulls of Shogun, South Park game, Project Draco, Class3 and more. MS always has the best line-up of arcade games between the three and people seem to ignore them, I wonder why? Next year is a great year for arcade lovers. 

People are always on Microsoft's case about lack of exclusives. In reality, they've merely diverged from their competitors to focus on digitally distributed titles. This year it was more apparent than ever, with a steady stream of quality XBLA titles that never let up.

The one xbla game i really want is Shadow Complex 2 but i'm sure a few of those will keep me entertained.

Because people prefare Retail games? BTW Minecraft and South Park game are not exklusives. 

But as you say if you prefare arcade games Xbox360 is the one with most.

The South Park game, South Park Tenormans's Revenge, is exclusive http://www.1up.com/news/south-park-returns-xbla-tenormans-revenge ofcourse you may be mixing it up with http://en.wikipedia.org/wiki/South_Park:_The_Game

This,  honestly getting tired of arcade games,  only picked around 10 this year..
