I was looking at some commercials of those handheld games that were popular in the early 2000's. I remembered one that was based on robots. You would scan the barcode and you would get a new robot or part. Does anyone know what this game was called, I've been looking and can't find this game.
Those things were all pretty bad. Here is an amusing review of one of the main ones. Barcode Battler Review (attempted) - YouTube
I think the newer Digimon cards had something like this, but I don't recall if those Digivices were based on the card scanning or if that was just a perk.
I remember seeing Barcode Battler commercials and thinking it looked so cool. I wanted to go to a grocery store and start scanning boxes of cereal and stuff just to see what would happen in the game. Never got one though.
