So what you are saying is
3ds has no games (or gaems if you want to continue an old joke).
Welcome to the prepare to be flamed side.
Though seriously I am also at a loss, even more so if you went through the GBA and DS -- 3ds does not sufficiently improve on anything there, and certainly does not act as a replacement (if you have a DS you can just about skip the GBA, though you would be missing out). It also lacks much of the third party stuff that made the GBA and DS what they were for me -- most devs that did good stuff on the GBA and DS had either gone pop (game industry and all that), gone andrIOS or at best were doing token efforts and nothing that might hold interest.
I also see Youkai Watch being praised. I take it you all never played Medabots (skip the AX fighting game), Dragon Quest Monsters: Joker, Robopon, Demi kids (go for the dark version -- light version is generally considered the easy mode) or one of the "generally far better than pokemon" pokemon clones that at least were on the GBA and GB/GBC. See also telefang, Jade Cocoon (which if you are fans of Ni No Kuni probably wants to be played if you missed it), metal walker perhaps and maybe custom robo. Lacking competition on the 3ds does not mean it lacks competition.
That said while I have the essence of flamebait uncorked. "Bravely picked the Default settings in RPG maker" is apt. I really do not get what people see in that game/franchise.
