I probably won't be doing this (installing UT2004 on my new laptop and not UT2003) until later this summer, but I was wondering how many UT2003 maps (stock and custom) work in UT2004? Obviously, most if not all of the stock maps now have UT2004 versions, so I guess this question mostly pertains to custom maps. What's a good percentage of how many UT2003 maps work in UT2004 (not including the ones already converted of course)?
