Which Battle Frontier Facilities did you beat?

[Super Mario the Hedgehog]

By that, I don't mean just one run. I mean to the point where you beat the Frontier Brain.

For me, I beat Battle Castle, Battle Arcade, and Battle Hall.

I have a silver print at all Facilities in Platinum.

 

[Super Mario the Hedgehog]

Awesome! Personally, i'm just too lazy to beat all of them to be honest. After beating the Champion and exploring all of the region in a game, things get a bit stale for me in Pokemon. I still play sometimes, of course, but I'm not really that into it at that point in time.

Silver symbols in Battle Pike, Battle Pyramid, and Battle Arena. Haven't gotten to it in Platinum yet.

 

[Pyro]

Silver in the Hall, and that's it.
