I think the Mario & Sonic Olympic games had Spike Gates in dream Events but I can't recall which ones.
I think Sonic Generations had Spike Gates but I'm not sure.
It's why I didn't add it to the list in case of misinformation. I'm hoping others will freely edit it, add to it and refine it where I could not.
When I make brand new articles, I like being first on the newest things, but usually I make articles on the minor, little things. Like stuff from the old Sonic cartoons here and there.
