It dies when people stop talking about it.
Simple as that, no?
--The End--
Pretty much!
Last GB title: Pokemon Red/Blue. Great game.
Last GBC title: Harry Potter and the Chamber of Secrets. Great game.
Last GBA title: On schedule are Deal or No Deal, Enchanted, Frisbee/Frisbee Golf, Cars Mater, Arctic Tale, Crash of the Titans, SpongeBob's Atlantis SquarePantis, Spyro Eternal Night and lots more.
Would be brilliant if Nintendo did have Mother 3 ready and were waiting until there were no more GBA releases left to release it.
