About this Site

OpenSourceMacGames.com is a simple list of games that will make almost every Mac user really, really happy. We made this page to be a handy reference for all the folks who are buying new Macs and don't know about all the great stuff that doesn't come pre-installed. Most of all this is a work in progress. If you think we're missing any totally clutch Mac games, let us know: info@bestfreesoftwarelist.com

Note to software creators: first of all, thanks so much for making totally rad mac games.

Second, if we linked to macupdate or versiontracker as the download page, it's because we think your download page is too confusing for new users. It's usually very easy to improve-- just add a big 'Download Now' link towards the top of the page, without too much clutter around it (use mozilla.org or adiumx.com or bittorrent.com for inspiration).

Here's some more unsolicited advice for getting more people to download your software:

if you have a nice icon, show it off prominently.
put a download link and a screenshot on your front page.
if you use mirrors, use a script to pick a random mirror and just give people one link that says 'download now'
if there's any way you can avoid sending people to the sourceforge download mirror page, you should (we know it's not your fault, but it baffles lots of folks).
if you really want to make things easy for people, and you have a cross-platform app, detect what OS they are on and give them the correct link.
test your page on a novice! See if they can understand what the software does and how to get it.
