I play in spurts, maybe once a week. I last stopped just after beating the third kahuna and taking the boat to rescue lily.
I don't know if it's due to pokemon shuffle scratching the itch between generations, the game not having the ORAS tracker that lets you know whether you've caught everything in an area, or whether my interest is just waning as I get older and have other things to do, but this is the least-engrossed I've ever been in a pokemon game.
