What's more they do update the listing so expect a new addition every so often, today for example I just found out that Desert Strike was added to the listing!.
However there are a number of downsides, one being that some of the games although look like the originals and almost claim they do are in fact not, but actual remakes or clones of the original releases. Also the other downside which may put a few off, some have claimed it installs spyware on your system, HOWEVER I have yet to see any spyware on my system, I run an antivirus, Spybot and Malaware. The only thing I can say is when installing, ALWAYS check what options it gives you for any special offers and click no, so many are doing that now which is annoying but I didn't see this in my installer of Jogobox!.
The client does need a service to run in the background called Jogoboxservice.exe which I have repeatedly asked them what it does, but they did not answer. However to my system scans it doesn't call home but mainly a service to run the client.
