Age of Empires:
-More RAM in computers would allow for significantly more units at once without lag or crashing, allowing for much more epic gameplay
-More powerful servers would allow for server hosted matches, which fixes lag issues, hacking issues, disconnecting issues, and more. Multiplayer would be 9000x better.
-Better graphics would always look cool

It's a shame that the company that made it shut down, if they made a 4th age of empires game with the new technology, it would be amazing. Yes I know about age of empires online, but it honestly isn't the same-it's cartoony, less strategy based/in depth in terms of gameplay, based on a different time frame, and overall just not as good.

Star Wars Battlefront. Imagine that with great graphics.

There is already a new one being made.

But it won't be quite the same. Like Battlefront 2 was good but didn't have the same feeling that Battlefront had.

Crash Team Racing Online = My life project :3

Because in Battlefront two you were able to play as the heroes.

a good harvest moon game

I would redo the feature in Wonderful Life where you restart back to the point before you die. There's no point in continuing if you just keep dying. Either that, or make a Harvest Moon game that involved a similar concept of Animal Crossing New Leaf where friends can check out your village and you can play some games together, but a little better.

I feel like they're milking (no pun intended) the series on the DS / 3DS too much. I'd love to see a Wii U version.

I think DICE is working on that. So brace yourselfs for the most annoying glares ever!

Oh i got more.
Battlefield 2142 with frostbite 3
My god, that would look incredible. Imagine it, gigantic mechs leveling houses, everytime they would hit the ground hard a huge cloud of debrie is made along with a crater of where you landed. It would be mass cahos

Call of duty 1,2,3 (lets face it, it would look like any other cod game)

Super Mario Sunshine

I want to say Golden Eye, but it was remade on the wii (but lets face it, FPS games on wii dont go well)

Doom

Quake 3

Donkey Kong 64

Gta 3

Battlefield 2

Halo 1,2,3

Battlefront 2

Wolfenstien

Mario kart double dash

Zelda twilight princess

Wii Sports

It would also be nice to downgrade games to older engines, features, etc.

I felt that in the Halo and Call of Duty series, the peak of gameplay quality and fluidity were at Halo 3 and CoD4 respectively. The games past those two in each series felt rather clunky as the series progressed - BO2 and H4 felt like garbage to play to me. I know some people like the more realistic feel, but FPSes in my opinion have been getting worse and worse as time goes on. Especially the transition from CS:S to CS:GO.
