You don't need much room at all. If you have room to play any other game you have room for a Wii + waggle. Especially since playing with the Wii is a more relaxed process than with a standard game controller.
Add to the fact that Wii is small as fucking hell, and I wonder why you even brought that up. It seems to me you aren't willing to give Wii a chance, PD. But after the GC, I'm pretty sure you're burned pretty bad as a Nintendo fan.
No, I was burned at E3. All the hype, all the interest. Fuck, I spent like half a week creating more hype for Nintendo on the internet through Broken Saints than they ever did lol. Two disappointing E3s later I'm still waiting to be impressed. Right now, I see a bunch of terrible minigame romps, some ports, and a couple good looking games scattered about.
I remember hearing about how FPS games on the Wii would be amazing. Hell, I spent like 30min typing up that Game Informer article on Red Steel and posting it on GAF. Yes, I was extremely excited. I remember reading how the AI would be like FEAR's AI, and how quick 360degree turns with the Wii were on pace with mouse controls. But so far, Red Steel and MP3 have rather clunky controls that aren't smooth, especially when you try to turn. Maybe that will be fixed in the future.
Nintendo has shown off tons of minigame romps that NO ONE cares about. Why? So they can potentially get 50 year old women to buy a videogame system. Why aren't they showing a nearly equal emphasis on hardcore games for the hardcore gamers who they already sold 2 billion+ games to? Zelda, yeah. Mario, yeah. What else? SSBB, true, and guess what: it uses the Gamecube controller. Fire Emblem, yes, which doesn't use the controller either. Nintendo seems bent on creating tons of new IPs for nongamers, but what about new IPs for more casual/hardcore gamers? Project Hammer? lol
I'm going to get Zelda on my Gamecube and enjoy it, while playing through RE4 again with component cables. I'll get the MP games again and try to beat them. Heck I never finished Wind Waker's final few fetch quests, so I'll play through that again. By the time I'm done, maybe Nintendo will give me an incentive to buy their new console.
The Wii is going to flounder in the US over time, and maybe then Nintendo will realize that alienating your bread and butter customers in order to gain a group of people who have no interest in gaming...is not a good idea. Good luck selling systems to 50 year olds Nintendo. Might as well try to sell them a rap CD
