Take a look at Canada's Wonderland thrill ride offerings: https://www.canadaswonderland.com/play/rides-thrill
I think the Skyhawk, Sledgehammer, or Soaring Timbers attractions would be awesome additions.
X Base never really felt like a cohesive area with its two coasters and nothing else. I don't think the giga will make it much different; at least one awesome flat ride and maybe a food option would round it out. And people joke about bathrooms but even that would help it feel like a distinct area of the park. I hope the giga is the start of this kind of expansion!
I agree. There are really only three thrilling flat rides at the moment which is something I find the park is kind of lacking. I hope we'll get something new in X-Base after the giga to round off the area.
