Seriously. This is bloody life changing!
When games have user created content — user made maps, tracks, levels — I tend to ignore them for the most part. There's something just a little off about most of them: they lack polish, they're inconsistent, don't fit into the themes of the game, etc. But this track, The Cave, on Trials Fusion is absolutely worth the hyperbole of the above headline. It just might be the best user created content I've seen in a video game ever.
I'm making the call: I think it's better than any track RedLynx themselves made in Trials Fusion. It is seriously that good.
It has everything. Fire, dolphins, caves, underwater sections, mindbending physics, exploding airplanes, dramatic viewpoints, perilously difficult obstacles. This is the ultimate Trials track. Literally, there is no point creating any more after this one. The Cave cannot be beaten.
Just for reference, this video is of the very first platinum run on the track.
