Most versions are compatible. 2002 is about to loose support from Microsoft and shouldn't be considered an option. Office 2007 is decent, and 2010 is my personal favorite. Office 2013 is build for Windows 8 specifically. It has a metro theme and is build to work well with metro-tiles.
I know for a fact Office 2003 or anything before that won't work for Windows 8.
Oh? I'm using it on 8.1 no bother. Have to install it using Compatibility, though... Simply Rt click the Setup.exe file and choose 'Troubleshoot Compatibility' Once installed, d'load File Format Converter from M'soft to enable Word to open later versions...
