2008 and beyond, prime years for the Wii

[your mother]

The Wii may not be able to handle the Unreal 3 engine, but I don't think Unreal 2-spec engines are beyond its capabilities.

Seeing that UT2004 is still a very nice game visually (it's held up quite nicely over the years) I think most Wii owners won't be too displeased with that quality standard.
