Sure you´re right, kesadisan, but then you´d have to put Infinite Space and SMT: Strange journey in here too.
But for people like me who have to wait for english releases these games can´t be taken into consideration due to language limitations. I´ve played them partly, but to really vote on them I just have to understand more of it. So this poll should maybe be called "best english released game of 2009", that would be alright with me as English is the language established here at ds-scene?

For my vote: all of these games are very high standard titles, I really enjoyed all of them. So I´ll go with the game I couldn´t put aside until I finished it, which has to be.... (drumroll) Chinatown Wars. Yeah, not really innovative, but god was that addictive
