Just felt like it honestly, and it's 2014 so eh, I dunno I wanted to see IB again. Like seeing your Pokemon in the daycare center after leaving him there for 56 game hours.
I don't know why people ask for console recommendations. Just get whatever you want. The 3DS has a good library of games now and I'm sure the PS4 will too as time goes on.
I say 3ds because the ps4 great exclusives don't come to late this year and there are too many of them. 3ds you got Zelda,pokemon,fire emblem, shin megami 4 and bunch of great 3ds exculsives.
If you absolutely want to get a PS4, wait till they produce the next batch.
Hopefully those won't be wobbly, and will have games that aren't just multiports.
