Uhhh... any preference? You can't just expect people to give you titles if you have't narrowed it down. Meet us half way.

Well, get a 3DS and transfer all your DSi data over to it, sell your DSi get a PSVITA.

3DS:

Mario 3D land, Mario Kart 7, Metal Gear solid, Heroes or Ruin, luigues mansion, Tales of the Abyss, and Resident evil Revelations. Also several of the eShop games and Swapnotes/letterbox

PSVITA:

Uncharted and little big planet


But on the current systems you have if you want to spend the money on the PSP and DSi.

PSP:

Monster hunter games of any kind


DSI:

Sotorobo: Red the Hunter (you can also play this on the 3DS)


For the 360 get Skyrim. For the Wii if you can find it get Tales of symphonia Dawn of the new world.

Don't get Skyrim on Xbox: PC is where it's at for ES games.

For the DS, get The World Ends With You and/or Magical Starsign.

I would suggest not bothering with the PSP as it's a dead console, but a good game on it that's damn cheap now is Final Fantasy Dissidia Duodecim.

Wii - Skyward Sword says HAI

Havn't played it but I heard Xenoblade is pretty good. For Wii.

Completely forgot about Skyrim on computer. I'd go with that and absolutely Skyward on wii.

Should probably get Xenoblade, once I'm done with SS.

I second Xenoblade for Wii and Skyrim for PC. Should keep you entertained for a long long time...

Skyrim on xbox is good... if you don't have a computer good enough to run it then it's not like you can't get Skyrim because the xbox version is terribad.

obviously, skyward sword, and some other zelda games off of virtual which in itself offers a multitude of epic games.

xenoblade is a great game, skyrim too, and for ds i recommend chrono trigger since not many people have played it, and it IS an awesome game.

i myself just finished mario 3d land and that is a trly awesome game, the 3d wowed meh the first time i played it, and the level design is quite nice.

skyward sword, 'nuff said
