Pretty much anything for the tg16/pc engine on ebay is gouging now days. Especially with Buyitnow. The only time one might find a good deal is if the listing is an auction started low. The only downfall with this is lots of time the auction will get up the the amount of the other gouging buyitnow sales because everyone starts to think that is the going rate for said game since that is all that is available. It's kind of crazy but in the last 2 months alone I've seen sellers raise the price of a game they sell by almost $10 every weak and I think they get away with it too because of the supply and demand. It artificially raises the going rate of said game when the supply is not there.
Pretty soon, the only way for anyone new getting into the system to be able to play any games will be to get a Turboeverdrive and a stack of CD-Rs. It's just sad because I really like helping others get into playing these systems and the lack of games on the market just can't match the interest being shown for it now.
There are some exceptions to the U.S. Game gouging because the market pretty much takes care of that itself. No one is going to pay more than say around $20 tops for keith courage, final lap twin, World Class Baseball, JJ and jeff, galaga 90, power golf, Aliens Crush, sonic spike, moto roader, Vigilante, Pac-land, Victory Run, Dragon Spirit, dungeon explorer, tricky kick, Side Arms, TV sports games... Basically the most common of the Turbo Hu card library.
