Has there been a Magic the Gathering game on any platform? I've seen Yu-Gi-Oh games for gameboys, but I don't know how you would play a game like that on an Android, lol.
There's plenty of MtG games on PC. I wouldn't mind trying out one on Android. Not sure why they wouldn't put one out if it isn't already in the works. They'd likely try iOS first and perhaps they are running into problems with the in-app purchasing issues because the MtG folks are only interested in players buying booster packs.
