Normally. I will probably save the challenge run for Shining Pearl, if I ever go back to the Ultimate Flying Monotype Challenge I started on here...last year? I don't even remember, haha. But I'm not one who really does things like this, so I'll just play Brilliant Diamond normally.
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
for my first (and let's be real - probably only) playthrough i think i'll just play it normally. i'm not a fan of restarting games, so i'd have to pick up the second version to attempt any sort of challenge.
