I assume he might wanb to have the 1.0 version for using some older cheats for the SP campaign as there's many that utilise the bugs in 1.0. I can't come up with any other good explanation. Maybe he just wants to see the differencies, but that sounds quite stupid too.

Back to the question. I myself have two different versions of MoH:AA under the same OS, on the same PC. The one is my usual MoH:AA with custom maps, EZRcon and some other custom stuff (e.g. no title screens PK3), while my pure version of 1,11 only has what you get straight out of the box with the 1.11 patch, plus honesty.cfg. Very handy for daily playing and match use (especially Pandora), as you don't have to worry about moving away mods for matches, which is waste of time and stupid. It takes some extra HDD space, but works well.
