I look forward to the day, with great anticipation, when some company makes a game that has the option of dual-wielding two WM+ Wiimotes. Such possibilities... Or strap two more wiimotes on your legs for a poor-man's motion capture system, but that's probably ridiculously excessive.
Either way, dual-wielding Wiimotes=win.
On that note, are there any other games that support dual wielding Wiimotes? I know House of the Dead does, and there's this one Wiiware title that does, but I'm not sure about anything else.
