Tancred Dyke-Wells, the creative director of Kuju (the company behind the Wii's Battalion Wars 2), recently criticized many Wii developers for "under-exploiting" the little white console. We tend to take his word seriously, since we think that BWII "has just about everything that fans of first-party Nintendo games are looking for," as you can see in our review of the game.
Dyke-Wells' main beef with developers is with the way in which graphics are handled on the system. While the Nintendo Wii can't compete in the graphics department with Sony's Playstation 3 and Microsoft's Xbox 360, he believes that the Wii is a "pretty good piece of kit" that overpowers the GameCube "by a factor of two."
In the end, Dyke-Wells thinks it comes down to how much respect these developers have for their companies, their products, and their consumers, and we can't help but agree. The possibility of making a quick and easy buck is tempting, but we expect developers to make good games simply because they can.
