There's been an increasingly popular trend with multi-console games that I'm coming to like a lot. That is, not making the game with limited features just because it's on the Wii.
Take Rock Band for example, it was released a few months after the PS3 and 360 versions, and what do we get for extra features? 5 new songs! Not only that, but the World Tour and character creators have been scratched. Why? I'm pretty sure both of those could be done on the Wii. Not pretty sure, positive. But Harmonix feels they need a quick cash in, seeing that Guitar Hero III sold the best on Wii.
I mean I understand if the graphics aren't nearly as good. The Wii's doesn't have a top notch processor. But if parts of gameplay are left out, or if certain actions that were originally button presses have been made into waggle, I feel cheated.
Fast forward to the present and a lot of developers are doing their best to make the game equal on all consoles (excluding graphics of course). Two that come to mind are Guitar Hero: World Tour and Call of Duty: World at War (both by Activision). The developers have both stated that they have no intention of making the Wii versions any less featured than their 360/PS3 counterparts. Guitar Hero: World Tour is even going as far as offering DLC, a first for any Wii game.
So now that the Wii's been around for almost two years, I think developers are starting to realize with lesser graphics doesn't equal lesser gameplay on the Wii. And I'm liking that (as I only own a Wii).
