Nah it's Indiana Jones vs Batman, when Indiana Jones was still good.
It's also gun play vs beat em up, bright lighthearted humor vs darker edgier world, linear journey with open set pieces vs a more open city to explore.

I know they didn't make the cut, but for me it's a toss-up between New Super Mario Bros. Wii and Halo 3: ODST.

Arkham Asylum is essentially 3D Metroidvania - one of the reasons I liked it more than its open world sequels is exactly because of that design, plus it had really great gameplay - and of course Mark Hamill as Joker is spectacular.

Yep, which makes it so hard to choose. Uncharted 2 is the best in the series imo and Arkham Asylum arguably the best Batman game as well.
Batman is ahead by one vote, who ever wins is well deserved.

Well that prediction aged well. They did so well they deleted all the other options.

They are solid games but both a little bit overhyped imo, I personally think they fall short of later entries by a decent margin (Arkham City and Uncharted 4). Regardless I'd give it to Uncharted 2.

I voted for Arkham Asylum. Not only is the voice acting, combat, music, and atmosphere top notch, but what really sets Asylum apart is the metroidvania elements and the sense of dread the game gives you. It's not an open world game the way City and Knight are. It's a series of very closed spaces with just a few kinda open areas, but you can run from one to the other in like a minute lol. You're a lot more focused on the detective aspects of Batman to continue through the story, and it was all just so well done.

I'll never forget the first time when I was playing and the game made me think my game just crashed reminded me of Eternal Darkness.

Voting is closed and the winner has been chosen.  The 2009 Game of the Year is Uncharted 2: Among Thieves, and the runner up is Batman: Arkham Asylum.

This was an extremely close year with Demon's Souls being close in the running for a while.  Then we needed a second runoff vote, and even then the final two games were neck and neck the whole way.

So Uncharted pulled through in the end.
