Foreword: Entire post is not addressing Project Ukulele, which is a game being made by proven industry professionals who have made an insane amount of extremely successful games and proven their worth.
I give credit where credit is due.
There are an excessive amount of cheaply made, amateur, bland, slow, choppy, chuggy 3D platformers being announced and released right now that are just riding on nostalgia and "hey remember that 90s thing you loved!? we loved it too!". Lobodestroyo is the only indie 3D platformer coming that seems to have any decent polish and design, and seems to not be running at 10FPS. And even they're running on quite a bit of "remember Crash Bandicoot?". Clive N Wrench was awful, you could watch the frames fly by. FreezeME looks like it was made by going in a Mario Galaxy world editor (especially those pipes) and throwing assets randomly about. A Hat In Time tries way too hard to be lolsorandom while name dropping Banjo-Kazooie and having none of Banjo-Kazooie's charm. It's so sterile.
This is what happens every time there's a boom. There's a tiny bit of wheat, and a lot of chaff. Look at the hundreds of Minecraft clones on every app store. Look at the hundreds of Flappy Bird clones that still exist. Everyone can see the spotlight, and a lot of people want to be in it before it passes.http://en.wikipedia.org/wiki/Sturgeon%27s_law
Edit: "Back in the day, 3D-platformers were THE big AAA adventure games"
This is true. And then there were too many of them with little innovation or quality out of most studios. And then there were none. It happened to WWII games as well. It happened to Guitar Hero and Rockband (which fittingly enough is now seeing it's own resurrection 8 years later). It happened to the MMO and to some extent continues to (there's only 1 WoW but there are thousands of dead Korean F2P MMOs you've never heard of). It's happening right now with Assassin's Creed, "Bro Shooters", etc. And if we're not careful the platformer will die yet again before it even gets back off the ground. More choice doesn't mean people make more decisions, too much choice means people choose "not at all" - http://en.wikipedia.org/wiki/Analysis_paralysis
"There are so many games out there, so many great games (even if they're not 3D platformers), that we can afford to be extremely picky about what we like"
Precisely. My backlog is already 200+ games deep. Why throw money at sub-par projects? Rare made the best platformers I've ever played with way way way way worse hardware than exists FOR FREE today, and with a small team.
And to clear something up, I never said "I hope this project fails" or "I'm glad this project failed". I said "I dislike this project and here is my reasoning."
Make the forum great again.
