I don't know if that is the GBA's target anymore. Nintendo seem to have aimed a bit higher thsi time, you can tell it by its advertising and by teh games lineup. I am surprised Pokémon is not out yet! That says something.
Still, even if the audience was a bit higher (let's say 12~18), I dont know if today's 'gamer's would like a game like Elite. It needs a lot of time, you have to delve into the game, master it, and then enjoy it.
We'll see. I surely would be nabbing a copy
