I never caught & saw all of the pokemon in any game execpt my Pokemon dimond. I used an action replay for that, but i immediatley regretted it. All it was good for was knowing all the pokedex info, but u could just download a pokedex app for that now.
200 hours??!!!! I've not completed mine on platinum and I've been playing for more than 1000 hours!!!! ( don't know exact cause the thing telling you how long you've played for only goes up to 999:59. hours )
I completed it like, a year after I got the game. Cause I usually finish the game within a week. But back then, it took me 1-3 months to finish one Pokémon game, cause I was still kinda getting used to it. I was a deprived soul and didn't get a game system til the DS lite. :| First game being Super Mario Bros. and Pokémon Pearl. When I got Platinum, I spent all my time on it and after about two months (got stuck on the FINAL PART OF THE DISTORTION WORLD), I beat the game. About 8-10 months later, I finally got my friends to temporarily trade his Drifloon to complete my Pokédex.
(Never gonna attempt the Nationaldex, though.)
I don't usually complete my Pokedex's for the pure fact that I don't care for catching every single Pokemon.
I'm not Ash, so be it.
If I wanted to be a Pokemon master THEN I would waste hours upon hours to achieve a completed Pokedex.
