Alright. You got me. I haven't played Wonder so when I saw you added Yoshi on Mario's back, I thought that was a thing. I looked it up to discover the opposite and that he's an invincible "easy mode" choice alongside Nabbit, as well. A shame you can't just switch between those features for everyone to allow players to use their favorites.
I think the concept is neat on a first playthrough, but I am unsure of whether or not I would still find Wonder charming once I've seen all the wackiness. Mario games are generally quirky anyhow, but it's not their selling point, so it worries me a little to buy it. Elephant that spits water doesn't sound like a mechanic that can carry this title's price tag. Plus, I have no interest in playing with other... people.
Man, I wish this art was true. Yoshi deserves to be carried around for a change and Mario's expression here is perfect.
