It's a question many people are wondering... why write for Windows Phone? Well Greek developer Marios Karagiannis, the man behind Monster Up, has answered that on his blog. It comes down to having fun, not having it be his full time job, and he's happy with placing a bet on Microsoft.

I have placed a bet with Windows Phone. And not just with Windows Phone, but with the up-and-coming Windows ecosystem. For me right now, Microsoft is the new Apple. It innovated constantly in many fronts and has some amazing successes to show for its efforts. For example, the XBox came late to the party, but managed to level the competition in just a few years... Windows 8, Windows Phone 8 and the new Xbox platform next year will provide a unified ecosystem that will be unbeatable. My bet is to be involved in this as early as possible and this was last year when Windows Phone launched and I released my first game for the platform, Tetrada.

Smart thinking from Karagiannis, and yes, just as Microsoft are looking at the long game, so are some of the developers.

Monster Up is worth a look as well, by the way. As you can see from the screenshots, it's a cute little arcade jumping game you can find in the AAWP App Directory.
