I strongly disagree with you on the standpoint of the collection being a good value. The collection is $60, it has 3 games, so very simply each game is worth $20. I don’t consider the music player to be worth anything as all that is an interface to access .mp3 or .wav files.
Let’s break this down per game.
Galaxy came out on the Nvidia Shield back in 2018ish. It runs in 1080p and costs 68 RMB, which converts to about $10 US dollars. Yes, it’s exclusive to China, but I bet Galaxy in this 3D collection is going to be built off this pre-established framework. Why would it not? All the work has already been done. But for the sake of argument let’s say it’s not and Nintendo just redid the work, fine. Why is Galaxy in this switch collection worth $20 while Galaxy on the shield worth $10. Don’t forget the shield release also came with a brand new Chinese localization of the game's text. Additional work for a game that’s priced cheaper than the one in the 3D collection.
You are correct I spent $10 on a version of Mario 64 that runs in 480p. However, I find it harder to understand that the same game is worth $10 more with a native 720p output. Yes, the game does have new button prompt graphics to match the switch's layout. But aside from that, again there are no additional upgrades or quality of life improvements anywhere else. No 16:9 support, it’s HD but not confusingly not 1080p, and as far as my ears can tell all sound effects are still compressed like in the original. You're paying $20 for Mario 64, a game that’s 24 years old, and the only difference is now it’s 720p and now it asks to press the “+” button, not that “Start”.
Lastly is Sunshine the odd one out in this collection. Personally I enjoy Sunshine quite a bit, but I know it’s generally looked down upon. For some reason, sunshine got a 16:9 update and it runs in 1080p. These are nice visual changes to the game. But, again, it’s the same game as it’s always been for better or worse. Because of how the Switch sees the Gamecube controller as a pro controller, this game is missing the pressure feature that was in the original release. Of the 3 games, this is the one that probably needed the visual touch-up the most. That said I’m far more forgiving of this one as its the only game in the collection that didn’t receive a digital re-release. While the game sorely needed tweaks to its gameplay, among a lot of other little improvements. That’s not what this collection offers, what it offers is Mario Sunshine, at 1080p for 20 bucks. It’s the only price I would be willing to accept. That’s about how much a PS2 game costs on PS4. However, even the original PS2 version of GTA San Andreas on PS4 (a game I consider way better than sunshine) is priced at $15, runs at 1080p, has a full digital manual, and got added trophy support.
Graphics aren’t the only thing that can be tweaked in a collection of re-released games. As I mentioned graphics were just one of many improvements that were added when the games were given a second life. Nintendo chose not to take that path and instead just released the games as they were, in a higher resolution. Personally, since this was their approach I wish they did what Sega did with the Yakuza collection. It was a collection of 3 games, Yakuza 3, 4, and 5. You could buy the collection digitally for $59.99 or you could just buy the individual game you wanted for $19.99. That way you aren’t forced into buying a collection of 3 and 4, if you only really care about 5. If Nintendo did this I would not be saying that I found the price tag of $60 unreasonable or too high. It’s because I would have to pay $60 and get all three games when I really only care about one. Oh, and that's ignoring the "better act fast" aspect of this collection because for some reason this is a limited time offer only available till March? Ridiculous.
With all that said, I do wish you, and your family has a good time with the release. Just because my opinion differs from yours, I also understand that people have emotional connections to games. So hopefully all my bellyaching hasn’t rained on your parade too much. I also appreciate being able to talk to someone with a differing viewpoint and not having them blow up in my face simply because we disagree. This has been a pleasant little debate. Honestly.
Lastly, I am awaiting the day Nintendo decides to make a console that can compete with Sony and Microsoft. Will it happen anytime soon? Who knows.
