I'd like to see an option for this. Ever since 2.0, I spent a lot of time playing on Survival mode (see my other thread), and one thing about it that I particularly liked is that the "1-up" at 100 coins essentially translated into free power-ups. Especially when you're playing a random (or all characters) game and focusing on more than just a few characters, free powerups are much more attractive than a free life, and it makes coin collecting actually worth it. Somewhat-related, I'm trying to figure out what exactly determines which power-ups you lose if you get hit now. Is there a rhyme or reason to it? Same thing for what power-ups come back when you get a mushroom. If there are any specifics to this, it'd be nice to see on the Wiki page.
