I have an idea for a game. Remember that Pokémon TCG game they released a few years back on the Gameboy? Well, my idea is that a game like this is made with RMXP or some other game making software, only with all the cards from Base Set 1 to whatever set is out now (I don't know all the sets of the TCG)
I imagine it would be fairly easy to do. The attack system would need to be adjusted to remove a fixed amount of HP from a Pokémon, a prize cards system would need to be written (which I imagine would be fairly easy) and the deck system would be very difficult (what with the cards being drawn randomly), but I'm sure it's possible.
If anyone wants to make this game, feel free. I don't think I will, though.
That cave above Blackthorn City sure has changed...
