I think if they added an radar or something to help find the Blue Coins that would be nice.
Or better yet, got rid of the blue coins and made actual levels for those shines. Super Mario 64 DS added 30 stars to the game, so just do something like that, but instead of inflating the number replace those. Do that and improve the camera and I'd absolutely buy that package.
I would agree to that. I never found all the blue coins. They were so frustrating it was impossible to map out. There are some aspects of Super Mario Sunshine, that make it one of the better Mario games, but other aspects that make it awfully frustrating. I don't think I want a remake...I would rather have a new game that keeps the mechanics that work and gets rid of the mechanics that don't. Here are the things I would like kept:
1) Hover Mechanic for pinpoint accuracy with jumps
2) Mini challenge stages to get stars pushing the limit of your platforming skills
3) The Tight Rope walking and jumping...and basically open world with focus on vertical exploration
4) Sliding down walls and wall jumping
The things that didn't work:
1) The water gun mechanic mixed with limited water...was not enjoyable
2) The Race the clock to complete a task...with no idea where to go or where to look. Worse when you also have to use the water gun...and run out of water.
3) The story.
4) Finally the limited environments.
5) The Over World Hub to the other actual levels was clunky and not very enjoyable or easy to maneuver to the next level.
All in all, Super Mario Sunshine took everything that was in Super Mario 64 that was fun and made it better and perfect...but then they added features that actually hurt the design and made it worse. Super Mario Sunshine always excelled when the game felt more like a souped up Mario 64, and failed when it started moving away and doing its own thing.
