For me it was Ruby, by the time I got to the league game time was 99 hours
Wth were you doing in the game to take 99 hours to get there and how over leveled were you?
Training my groudon, I wanted a walerin before I challaged the league, getting my Raichu, Septile, kadabra, flygon and Marcargo to lv. 60...
and The regi puzzle took a couple of hours as well...
