I plan to do a mostly normal run, but with a couple of "rules".
For one, I'm going to box my starter. In my previous DPP playthroughs I always used my starter, so I think this will make a nice change.
And I'm going to research the levels of Gym Leaders+E4 before battling them, and not let myself become higher levelled than them. I'm hoping that'll add a bit of challenge and force me to strategize a bit rather than just OHKO stuff. xD
