Super Mario Galaxy - 109 stars
3 more stars: speed run (simple although my arm was left aching from all the spin attacks) and the hidden star (although “hidden” is overstretching) in dreadnought, and a purple coin star in melty molten galaxy (fairly straightforward). The hardest star was definitely the hidden star, just because the time limit was fairly tight (30 seconds) - if I’d been given 5 seconds more I’d have completed it fifteen minutes earlier.
