I beat 5 video games in 2009 and matched it with 5 beaten games in 2010. I beat the following Nintendo DS games in 2010:

Mario & Luigi: Bowser's Inside Story

Castlevania: Harmony of Dissonance

Dragon Quest IV: Chapters of the Chosen

Professor Layton and the Curious Village

Dragon Quest V: Hand of the Heavenly Bride

I played the Nintendo DS mainly this past year with some party games on the Nintendo Wii and some short gaming sessions on the Playstation 2. I hope to play through more games on the Playstation 2 in 2011 since I only have Dragon Quest IX left to play on the Nintendo DS. I might end up getting Dragon Quest VI when it comes out, so I don't have to worry about having troubles finding it later. I am not sure if I will wait to play Dragon Quest VII that I have for the Playstation or not. The games are not linear, so it probably does not matter. Here's to a good gaming year in 2011.
