I actually didn't know that Wario World was 3D, but if I see it cheap I might give it a go. I don't think WL4 is as enjoyable as WL or as challenging as WL2 but fairly good nonetheless.
Certainly the trend for platformers having more collectables roughly coincided with the advent of 3D and influenced the direction of games such as SM64 and reached it's zenith in DK64 which many people dislike for that very reason.
As well as the Mario series becoming more linear, I would also like to see a 3D Mushroom Kingdom. I do like the freedom of SM64, but I'd like to see a different direction now. Judging by Galaxy though, the series is moving towards a combination of 2D and 3D & linear and free roaming, and I think a strong argument for this direction can be made.
Maybe I should give it a second chance?
