I'm curious about something: why have so many folks have packaged up their games in .rar instead of .zip? Zip functionality is built into Windows and MacOS, and .rar requires a 3rd party app to package/extract. I was playing some of the compo games at a friend's place last night and we passed on the ones that were packaged as .rar since he didn't want to bother downloading winrar or whatever was necessary to extract it.
Is there some advantage I'm not seeing of .rar? It just seems like it's a PITA.
I had troubles back in the old windows XP days with WINZIP. WinRar was more flexible and supported more files. Also back then WINZIP didn't come with the OS automatically if I'm not mistaken. I never questioned my usage of .RAR files before as I never had anyone complain of it before. I can offer my game in a ZIP file if this is any inconvenience.
And I just went trough the whole thread and I got many answers :)
