We used to have Archies in school- I never really liked using them that much, although it was possible to format 720K MS- DOS disks on an Amiga and then port text files etc. over to the Archie, which helped for some school work.
I only saw a few games for the Archie but most seemed at least reasonable, though possibly nothing that couldn't have been done on the Amiga with a little work...
I think I do remember Zarch on the Archie, and it ran faster than the Amiga version (Virus). Wasn't Zarch/ Virus first coded on the Archie before being ported over to the Amiga?
