Well...
Lukewarm start for Mario & Luigi; terrible start for Youkai Watch. Terrible start for that FuRyu Vita game as well.
Don't know what to make of Civ Rev. It's not a disaster, only a little bit down from the PS3 game, hardly seemed worth making though.
3DS has held very well. PS4; WiiU and Vita are all doing well compared to the same time last year as well (well Vita less so, but considering it's had nothing relevant for a while it's decent).
