We talking about the fyre lobby or the Halloween one?
The fyre one did have multiple paths, but it was still the same parkour and it had no variation.
The Halloween one got progressively harder but you couldn't join in on the later stages without completing the early ones. The cobwebs were glitched with NCP, which sucked and I never made it past the second stage.
The current lobby has 4 parkours, which are all nice. I didn't really like the fyregames lobby in general, but the other ones that I can recall were fairly nice, I remember when you could get out of the lobby that was the version before the Halloween one. The buildings outside were massive, the only problem is that I was only able to explore out there once :/
