Obviously it depends on what games appeal to you but the most time consuming are easily Hyrule Warriors and Monster Hunter 3 Ultimate.
Other great games that are a must are Bayonetta 2 (which you already want) Pikmin 3 (which I think you want) LEGO City Undercover (IMO, the best LEGO game ever made) The Wonderful 101 (same people that made Bayonetta, great under rated game) Donkey Kong Country: Tropical Freeze (I am not a fan of 2d platformers and I never owned a Donkey Kong game before this, but I got this the other day and I am in LOVE with it, highly recommend)
The list goes on and on really.
But if you like time consuming games, I hope you are looking forward to Xenoblade Chronicles X (300+ hours long for a completionist) and Splatoon (this will obviously be like a Mario Kart or a Smash where you just want to keep playing to get better and better)
