No, I don't mean that, but the Luigi in Mario Party 2 sounded a lot different to the Luigi in SM64DS. And also, when Mario wins something major in MP2 or MK64, he says 'Hee-hee, I got it!', while in SM64, he sticks with the classic 'Here we go!'
Also, the Mario and Luigi sounds are a lot different.
