Mac Games Arcade is a way of downloading and browsing a huge number of Mac games directly from your Mac's desktop.
The good news is that the majority of the games are pretty good covering everything from shoot-em-ups to role playing games. The bad news is that they're not free and some of them can take a long time to download. You can however test out most of the games with preview versions before you part with any cash.
The developers have clearly taken their inspiration from the iTunes store which is no bad thing although it doesn't quite reach the heights of iTunes. Although games are organized by category, there are literally hundreds to choose from and none of them are rated. It would be much more useful if there were user ratings and suggestions of related games for those users who were unsure of what to choose.
Mac Games Arcade is an excellent idea and concept that will keep any arcade games lover happy for more than a few hours.
