If you have an good internet connection, you may want to download Machines Of Destruction here.
It's a nice little game if you want to waste your time.
I give you the hint to use AIM/Yahoo/ICQ to contact all about your current IP.
If you want to spend some time...
wow, the makers of this game have a good amount of other games as well...
I never visited the site before...
The games are a bit big to download for me, but I have most of them on CD.
