If you haven't played Monster Hunter on 3DS I suggest giving it a try, you may be able to lock hundreds of hours into it. Also, maybe give Bravely Default a try for 3DS. I got the demo and immediately bought the game shortly after. Rune Factory 4 isn't that bad either for 3DS I spent a month playing it and still haven't completed everything. Harvest Moon: A New Beginning for 3DS is pretty fun too. As for Xbox you've pretty much played all of my favorites lol If you haven't gotten the DLC for Skyrim yet I might suggest that, all together they could add a bit to your game-play value on it. X-Com was pretty fun for a couple weeks, but after beating it, it sort of lost its replay value to me. I don't know if Dark Souls is still free on Xbox live with the Games for Gold thing going on now, but if you got into that seriously it could easily last you until September. =D Hope I helped!

I played 1 & 2, I haven't played 3 because I didn't like the first two enough to get it.
