Tough call. For console, I definitely logged more hours with Xenoblade than anything else (still logging, actually), but it's designed to be a much longer game than most others. I also had an absolute blast with Geometry Wars Galaxies, Kirby's Epic Yarn, BIT.TRIP Beat, Zack & Wiki (another one that I'm not finished with yet), and even Wii Sports. I'd probably go with either Geometry Wars Galaxies or BIT.TRIP Beat.
For handheld, Picross DS is easily my most played (I still play it almost every day), but I might give the slight edge to Ghost Trick. That game was just so awesome and had me alternately laughing and frowning (from thinking so hard).
