Even though I own 4 generation IV games (Heartgold, platinum, diamond, pearl) I honestly wouldn't ever consider doing this, and between HG and platinum I have 1500 hours playtime. All it amounts to is getting your starter pokemon, finding a good xp area, and grinding the hell out of it. I remember when I first played pokemon Red version, because I chose charmander and saw thanks to the little nintendo power book that the first gym would be a poor choice without more power, raised charmander in viridian forest high enough to learn flamethrower, then let it evolve to charizard (level 45). It was almost level 80 by the time I hit the elite 4.
The *only* thing this entire little game experiment seems to amount to as far as I can see, is to see how much of a masochist you are towards grinding and how many times you like to visit a pokemon center; When honestly doing the battle frontier for the 10th time probably *is* more entertaining, or swapping friend codes and raising teams to battle friends. (I've EV trained ever single uber tier and OU tier pokemon with dual 31 IVs from breeding for choice stats and moves, and raised them all to level 100 across those 1500 hours)
