Did you never play any 90s fully 3D platformers? This is what they were all like. There will be proper platforming, but it's specific and usually tied to reaching a major collectable. Individual levels in Rare's 3D platformers were almost like their own hub world, with lots of smaller challenges you could do. 3D Mario is different, with the goal being selected on the screen before the level begins, but even in Mario 64 and Sunshine the levels are very open.
Also, remember that this is the first level. Mumbo's Mountain and Bo-ob Battlefield both had a similar simplicity to them- a big space to run around in and try out various moves, and get a hang of the game's mechanics.
Like you said, 3D Mario is a lot different. The emphasis in 64 was never in running around, gathering up all these stars, each one involved a specific mission, usually making high use of Mario's acrobatic movesets. My complaint isn't that Yooka-Laylee is open, more that the world itself doesn't make the best use of the space its created to emphasize actual platforming.
That's a good point about Bob-Omb Battlefield, but for the best example of environmental consistency in an open world platformer I would bring up Jak 1. The very first world has a ton going on, yet it doesn't feel like a floating island populated sparsely with scattered test obstacles. It really feels like you're playing in actual environments, right from the first island. I've never played Banjo but I've heard it has the same kind of attention to environmental detail, making it even more surprising the team has seemingly "dropped the ball" in this regard.
Yeah this footage has basically just told me to not be interested, which is what I should've expected, seeing as the Banjo games never appealed to me before either. The jumping/platforming that I saw didn't seem satisfying to me.
But not everyone can like every style of game, and this definitely good news for fans of games in that style, this seems to be invoking that very well from what I can tell.
Still, so glad this genre, and genre-adjacent games are getting a resurgence. I have the Crash Trilogy, Knack 2 (seriously), and that 3D Mario (depending on which style they're going for) to look forward to.
I agree. I guess I should have specified this is totally a personal preference thing, collectathon fans and maybe even fans of "action platformers" like Ratchet will love it. My favorite genre is pure platforming, the more jumping and double-jumping over and on top of obstacles the better. Jak 1 being my favorite 3D platformer because of the platforming combined with believable environment design, but if games have to sacrifice those environments in order to preserve the straightforward platforming experience I'm fine with those as well, like 3D World.
As I said in the above quote though, a big part of the appeal in Banjo from what I can see in gameplay videos was the visuals, how the worlds looked. I really think in order to draw in the full "Banjo audience" Yooka Laylee should improve in this regard.
