>>12044165See, here's the thing. Maybe it's just me, but it seems like when a person wants to go back and play older gens that they missed, they are more interested in the main campaign, and not shit like BP grinding, and catching them all.
Sure, back when gen 3 was the latest gen, a battle frontier, move tutors, expanded safari zone were great, but they lose their appeal when we're now in gen 5 and there are far more easily obtainable pokemon/tutors/etc.
But again maybe that's just me. I went back and played emerald more interested in the campaign, and found it to be pretty much the same as sapphire and most of the changes you listed had no appeal to me.
