The lights are on
Nintendo hasn't exactly lit the downloadable scene on fire in recent memory. In fact, third-party developers like WayForward, 2D Boy, and Nicalis have dominated the WiiWare and DSiWare scene, not Nintendo. This strategy might sound good on paper, but with the rise of smartphone and tablet gaming, Nintendo needs to step up its efforts in order to make their downloadable platform more attractive.
...Modern Warfare Mobilized is quite beastly. I don't believe it has the following of Metroid Prime Hunters or Resistance: Retribution, but it's very solid.
Months ago I heard about a promising GTA clone called C.O.P.: The Recruit. Developed by masters of handheld techlogy (VD-Dev), I felt that it could be really, really awesome. Not quite.
