7 years and several dozen games later, Poke-mania is still going strong

OB1, by this point I don't think Pokemon games are increasing GBA sales, they are just selling to the already massive install base... while a GC game would increase sales much more noticably for that system. But as I said if they're just looking at it as 'which title will sell/make more', the GBA titles are the way to go. The variable really is how much they think the overall impact (as in sales of other games, not Pokemon) of those new sales they'd get on the GC would be if they released a full GC Pokemon RPG... that I don't know. But I would suspect that even considering that in most cases it still makes the best business sense to continue with the GBA games. Especially when you consider the massive cost differences to make said games.
