What shows would you pay good money to own episodes crammed onto a little GBA Cartridge? Keep in mind, eventually they will expand the capacity making it more worth paying $20 each.
I for one, because I'm watching it right now, classic Ren and Stimpy. The old show. Not the (Thankfully short-lived) Spike version, but the Classics, which Spike was smart enough to bring back instead. That show was a classic. And would go great with Spongebob.
Second, the original TMNT. I know, it's unlikely. The new one seems to be "in" now. And it'll probably never become a thought to Majesco. But I WANT THE OLD TURTLES!!
The Super Mario Bros Super Show.. Yes! If they could cram a week onto a cart, even better. Buy it by the week. Well, at least we'll have the DVD's.. I hope.
What else??
