Every single one of my Amiga games in on DD floppies. I even bought a pack of 50 brand new dd floppies the other day. The reason I don't use HD is because I don't have an HD floppy drive so it's more reliable to use proper 880k DDs.
I also still use HD floppies in my PC. They are great for transfering small files. I don't know why most people seem against using them. I have Loads of ICT coursework, and a few bits of electronics coursework, as word and publisher files, and there's still plenty of room left.
