A Mac user friend of mine tells me that I must distribute the MacOS X version of my game in a DMG, that it looks professionnal and is better that way. From my POV, DMG are a pain: - It's much simpler for me to handle zip files (both from the author and from a player's POV), - the game could be run from the DMG without being installed, which means I can't save files into the game's directory (I can if I set the DMG to read/write, but the player might then redistribute it altered) So my question is: should I really distribute my game in a DMG? Are there people who won't download it if it's in a zip file? Does it look so unprofessionnal in the Mac world? Thanks!
