>>48441659It gave you boosts for things which is cool. Not as good as O-Powers in gen 6 but still nice.
Worst feature to date is probably the original Underground in DPPt.
They were a downgrade to secret bases in RSE since you couldn't keep your friend's base, the decoration stuff was not well implemented at all, the weird limit on how many spheres you could hold to buy more furniture was dumb. The hallways were barren save for the digging spots and occasionally a trader. The fun parts of setting traps to dunk on your friends was neat but it was a really dry area for content.
Shouldn't even have to mention it was annoying as hell to deal with the underground to get spiritomb.
