I guess I'm envisioning the ability to bring just a disc and perhaps gamepads with me to visit family, pop in the disc and play without having to do a bunch of setup and file copying to their PC. I suppose to be realistic, if my cousin says "awesome disc, can I get a copy" i would say "sure"... i suppose thats not technically "personal" but its the kinda same as me installing it all on his PC for him. But not many in my family are PC Literate... so problems later on would cause headaches for them. Where as a dvd has it all ready to rock, ala console style. I mean I could just make a data dvd with the GameEx Installer, dotnet2.0, and some zipped up roms.. the only diff is that I would need to install it to use it, but it doesn't really change the fact that its a copy of GameEx on a disc with other roms.
