Dope Wars for the PPC - nostalgic memories of my calculator games days brings me to have great fun buying and selling drugs using my cell phone. I became a millionaire (close to billionaire) then I looked up and got hit by reality. MMM, best free download you will ever do!
One of my favorite parts of this game is the customization you can do. You can add new drugs to the list, you can rename drugs, do whatever you want! Awesome.
