I never owned a GBA before my DS lite and I've never played a GBA game. I'm tempted to get the version of the G6 lite that supports GBA games but why spend the extra cash if I would never use it? Are there GBA games that are as good or better than DS games? Are DS owners still playing their GBA games or is it more a case of once you switch you never (or rarely) go back? What would I be missing out on if I opted for the cheaper cart?
