I find that in the Gamecube years Nintendo was really lost in regards to where to go with their established series. The move to 3D on the N64 really allowed them to update their series in a fresh way. Then on the Cube it was like "Okay. Now what?"
I don't think Wind Waker is a bad game but there were a few things I just didn't like about it. WW just didn't work in the execution and frankly I don't think Skyward Sword did either. TP was just blatant cookie cutter crap though and that's WORSE. Nintendo did manage to turn things around with Mario and Super Mario Galaxy, where they had a pretty fresh twist on the formula and the execution was also perfect. Super Mario Sunshine's problem was not that it did something new but just that the specific new idea it had in FLUDD sucked. Galaxy's space idea however was awesome.
You've made the point about Nintendo not knowing what to do with their franchises post-64 before quite a few times and I don't disagree with you. It's true that up to the Gamecube each generation before had brought changes and upgrades to the franchises because of the new abilities/challenges gained from stronger hardware. When Gamecube came out, Nintendo had already proven that they had mastered 3D space and games and all the Gamecube gave was more power in a way. Whether or not you believe new controls can add any value to breathing life into a series, with the Gamecube, they didn't have that luxery. It was still traditional controls. Personally, it seems to me, that Nintendo's response was to make some of the best entries in all of their series.
Although you state that Wind Waker failed in execution and Sunshine's Fludd sucked and Galaxy was a turnaround as though it were fact, I highly disagree with you on all 3 points. I'm not sure why you knock the Fludd device as it basically serves as the Mario transformation in the game. For example, just like the Bee suit can let you fly and hover a bit in Galaxy, Fludd let's you do that in Sunshine. It gives you some different options of mobility and gameplay challenges. Maybe you can't fly and soar like Mario 64 but it's overall usage/gameplay advantage was limited anyways. It's only used in a few spots. Frankly, I loved the Fludd device and especially the hover ability as it helped me correct/save myself if I made a mistake. It's one of the reason's why the areas with no Fludd are more challenging. You can't correct youself if you misjump. Those zones become easier when you replay them with Fludd but I could move a lot faster in them and I could have a bit more reckless abandon in them. Can you tell me how Fludd was so sucky because I don't get it. Heck, I could spray a little water on the ground and then slide on it and speed up getting around a level instead of walking and running. Those are awesome little touches.
The complaint that I hear way more often is that it lacks variety compared to Mario 64 or Super Mario Galaxy. In Super Mario 64, you go into 15 different worlds to find 6 stars (7 with the 100 coin challenge of each level) with a few hidden levels scattered around also and in Sunshine, you stay on the island, it all has the same estectic and instead of 15 different worlds, there are 7 parts of the island you visit with 8 missions and 2 extra shines hidden in them and 1 more for the 100 coin challenge. The rest of the shines are obtained through the main Delfino hub and 24 are obtained by getting blue coins and just purchasing them. And if people want to complain about that or they don't like Bowser Jr. or the Pintas or other parts of the setting or story, I understand that. Personally, I don't have a problem with any of it and like it. (Maybe not Bowser Jr. but he doesn't break the game for me.) But I disagree that it lacks variety.
That is my biggest complaint against Mario Galaxy. It just seems highly repetative. I seem to feel about Galaxy what a lot of people feel about Sunshine or what Insanolord feels about Super Mario World for all you hardcore forum readers. I just don't get how everyone keeps rating it so highly. I beat the game and got all 120 stars but didn't beat it with Luigi and that was a couple years ago so I thought I'd pop it in again and see if my opinion might be changed especially after all the high praise it got from the recent best of Wii lists done by staff and forumers. Sadly, my save file disappeared so I've had to start again from scratch. Absence has not made the heart grow fonder in this case. I've just gotten to the fountain again and played a couple missions in that and already the game has come off repetative and boring. I might just do a review of this game as a rebuttal to all the people praising it about why I don't like it but people complain there's enough negativty around here already so I might not. Mario Galaxy was pretty much the last game I played on the Wii before pretty much going on a 2 year hiatus from Wii. Aside from cracking out Rock Band here and there with some friends, I went on a TV and movie watching catch-up phase and only played a bit of handheld gaming. I personally feel that it was because I found Mario Galaxy so unentertaining that by the time I finished it, I was getting more enjoyment out of other forms of entertainment that I just kind of stopped playing games. On the other hand, I've played and completed Mario Sunshine 100% at least 5 times possibly 6. I never played Mario 64 that much either. Sunshine is an amazing example of how to do a 3D platforming game.
At this point, I've written another essay which seems easy for me to do lately but just touching on Windwaker, I haven't played many Zelda games. As of right now, I've only played 5 of them (although I've currently got a copy of all but the GB Color games) and of those 5, I've completed them all once except for Wind Waker which I've played through and completed 3 times and enough time has passed that I would be willing to play it again. All the things that people cite as flaws, I never had a problem and I totally enjoy sailing.
