For Super Mario 3D All-Stars, the lack of Galaxy 2 makes it a no deal for me. Galaxy 2 is not only by far my favorite 3D Mario, but is also the perfect continuation of Galaxy 1. Takes the basic concepts Galaxy 1 did but expands on them with an insane amount of new gameplay variety and a greater challenge. If I was to purchase this collection, after playing Galaxy 1, I'd want to play Galaxy 2 right after, and that'd require me putting my original Wii disc, into my Wii U and playing the game in Wii mode. Well if I have to do that, then I might as well just play Galaxy 1 the same way on my Wii U using the original disc as well. And if my Wii U is already on, then I can also play Mario 64 since I got that as a Club Nintendo reward when they original ended that program.
So unless they made some major improvements to Sunshine, I'm not paying $60 just to play an HD upscaled version of that game. It's be one thing if they were doing what Capcom did with the Mega Man Classic and X collections, and split this up in 3D All-Stars 1 with 64, Sunshine and Galaxy 1, then had 3D All-Stars 2 with 64 DS, Galaxy 2 and 3D Land but they're not. As a limited run to celebrate Mario's 35th Anniversary, not having Galaxy 2 is just dumb and a major slap in the face to fans of that game.
For the Wii U ports, I personally don't mind them. I got to play all these games on the Wii U years before they came out on Switch so it's not like I have to buy the Switch versions. For something like Hyrule Warriors, I got about 30 hours of enjoyment from the original on Wii U before I got bored of the gameplay. So having a version of the game with more content actually makes me want to play it less since one of my problems with the original is there's way too much content in the game for what is basically a repetitive beat-em-up button masher.
Now something like Caption Toad which I loved I plan on buying it for the new content someday, but will wait for a price cut since the new content ended up not being that much more substantial from what I've seen. New Super Mario Bros U and Donkey Kong: Tropical Freeze are two games I could see myself eventually buying on the Switch again because I loved the original Wii U versions, and having faster load times would be great, but will probably wait until close to the end of the systems lifespan to do so when they've had their prices greatly reduced. Pikmin 3 is something I could see myself rebuying with the new content as well, but will probably wait until a price drop.
The only Wii U port I could see myself rebuying at full price is the upcoming 3D World + Bowsers Fury. Something about the way Bowsers Fury is presented kind of makes me think this new content could be pretty substantial expansion to the game. The way they're even calling the game, Mario 3D World + Bowsers Fury makes it literally sound like an expansion pack. According to reports, the original Wii U version was 1.7 GB, while the upcoming Switch version is 5 GB. Most of the time these Switch ports go down in size so for 3D World file size to become 3 times bigger, that kind of tells me there's a lot of new content being put in here.
Yeah, but even that is sad. Honestly, I was hoping for Super Mario 64 to be remade using the Odyssey graphics. I mean basically every texture you would need is there. But OK...some might say that isn't Mario 64 then. Fine...at least add some stuff to make the game more playable and valuable. I add the wall slide to make wall jumps easier. Add the extra levels from Mario 64 DS. And then maybe have all the extra characters unlockable after beating the game.
Super Mario Sunshine...I would love for them to add a Blue Coin tracker...maybe as something you get after beating the game. I mean Sunshine isn't a bad game, there are some issues with the camera and level design, but it isn't awful. I don't think the game needs to add too much. the HD upscale is probably enough.
Galaxy is the same, but like everyone else said Galaxy 2 should have been added. Galaxy 2 is like the Lost Levels. If it isn't in a collection I don't see them adding it period. I Nintendo should have thought this through more. Maybe they will make it a DLC for the package, or an update. That would be nice.
