I do not understand people's problems with re-used sound effects, specifically menus. Game franchises re-use sound effects all of the time, especially menu stuff. Mario, Zelda, Sonic, etc, all re-use sound effects all of the time, and we live in a world where many AAA games actually use stock sound effects, and nobody complains about that, so why is it a problem when Smash does it? The only reason developers do this is to save time and money. It's not lazy, it's basic project management practice.
