3rd Gen Trainer Hill & Trainer Tower

Trainer Hill was an area in Emerald and Trainer Tower was an area in FireRed/Leafgreen. In here, you face off against trainers, and try to do so at the quickest time possible. There are various different modes that can be played, and yes, trainers do have Shiny Pokemon in here. No, that was not a glitch. In the Japanese version, you could scan e-reader cards to add data to this area. While both areas are similar in many regards, they have some different rewards from eachother.

Did you ever challenge the Trainer Hill/Trainer Tower? What did you think of it?

(I'm still screaming over the fact that FR/LG had SHINY POKEMON IN THERE, THOUGH.)
