What game(s) will instantly sell you a system?

blizzard haven't announced any new games for a while, if they announce warcraft 4 i would be quite excited

the prospect of sony's first party studios already have me sold on ps4

games from level 5, shinji mikami, kojima productions would all get me worked up

Assuming they're good, games from these franchises: Streets of Rage, Sonic, Dark Forces/Jedi Knight, X-Wing/Tie Fighter, Rogue Squadron, and Zelda.

Wii U (already buying)=

-Metroid Prime

-F Zero

-Pro Wrestling (PLEASE)

-Custom Robo

-Star Fox

-The Legend of Zelda

-Wave Race

-Last Story successor

-Eternal Darkness

-Skies of Arcadia successor

Smash Bros, Mario Kart 8, Donkey Kong Country: Tropical Freeze and Super Mario 3D World will basically guarantee a Wii U purchase from me at some point.

Same goes for the 3DS. Pokemon X/Y, Ocarina of Time 3D (since I never played the original), A Link Between Worlds, Mario Kart 7, Super Mario 3D Land, and Animal Crossing: New Leaf are all games I really want.

Backward Compatibility is a MUST. :-)

Games:

- The ending of the Soul Reaver series

- A remake where Solid Snake takes down Big Boss

- The remake of FF7

- An Epic RPG (let see if The Witcher 3 can reach this level)

Already have a Wiiu and PS4 is coming day 1

Sunset Overdrive or Black Tusk's new game could make me break down and buy an xbone.

I am thinking of just waiting until MGS5 before I get a PS4. My backlog of PS3 games is huge and I need at least another year to beat all those games. Plus I got like 6-7 360 games I have to beat but 3 of them are 5 hour games and the rest are racers lol. So I hope I can beat all these games before moving on.

A HD remake for Final Fantasy 6

a brand new Fallout exclusive to xbone would be one of the only titles

Actually, if they make a sequel to Radiant Historia that'd sell me a system instantly too. Chances are it will be on 3DS though, so I'm probably already covered.
