999:59 for me! Much, much more according to the 3DS counter, however a lot of those hours listed in the 3DS are from starting the game, hatching eggs, checking the IVs and then resetting so not everything the 3DS says is actually saved, in game time.
The main difference for me from everyone else? I haven't even gotten to the second gym yet! When I first discovered the GTS and Wonder Trade I spent months just doing that it seems. I never had the fourth or fifth gen games so I had a lot of stuff I missed out on doing. Well then when I got sick of random trades I started finding shinies (about 1 per 100 hours) so I was able to trade them for legendaries, and then Pokebank came out and I was able to trade the pokebank exclusives for other legendaries, and then I came upon route 7 with the Daycare breeding and berry gardens and I have been breeding perfect pokemon ever since and I quite honestly haven't even stepped into the cave on that route yet, I have just been breeding (in reverse order that they are normally caught by) every possible catchable pokemon from route 7 down to route 1 (currently at Flabebe) and when I get them all at 5IV level, THEN I can finally move on! Thanks to the GTS and Wonder Trade and Facebook and this website, it is quite easy to get the abilities and moves you want on pokemon you need from other people in order to breed those abilities and egg moves onto the pokemon I already have. Honestly, Gamefreak could have released a game that was nothing BUT route 7 and I would have been more than happy with it!
