I'm starting to create a route and I wanted to know if there are any Red Bricks/Train Stations worth getting. I know you can't get Fast Build on Wii U but what about Super Colour Gun or the Train Stations.
On the WiiU, Red Bricks should most likely be ignored as you need to wait for 2 minute-long loading screens so that they can be purchased, which is what you need to do to use them in the run on the original.
For train stations, you can watch Trajan's WR or my PB, on the original version not the remaster, for an idea on on any train stations to get; I also have this video:
Which showcases a possible time save for the game.
The stations to get that are known time savers are the ones in Auburn, Pagoda, Airport (possible), Uptown (Remaster), Downtown (Remaster), Fresco (Remaster), and Festival Square (possible)
This is with the Any% category in mind
