I never would have thought about adding voices to the NES Super Mario Bros games, but hearing Mario and Luigi speak when picking up a power-up or getting hurt definitely adds a lot and makes it feel more modern and alive. The added story elements with the cutscenes are also something I would have thought was unnecessary as the NES was perfectly fine without them, but seeing them was actually pretty cool and didn't feel shoehorned in. I do however wish they kept Peach's joke about the princess being in another castle instead of swapping it out for something more serious.

Overall, Super Mario Advance 4: Super Mario Bros 3 is probably the definitive way to play Super Mario Bros 3 even if it's not my favourite, as it adds changes which improves the NES and All-Stars versions of the games, even if I think it's got very awkward controls due to the Game Boy Advance's 2 buttons being different placement to the NES controller.
