What are some games you can think of that had a big impact in the success of a system? Try to explain what about the game made it go viral, causing new comers to buy a console.

Wii Sports-(Biggest viral game ever) Motion controls done right.

Gears of War. Resi 4 started the over the shoulder TPS, Gears of War brought it to the mainstream.

Smash Bros-Nintendo Crossover fighter. How does this work? It's just so crazy enough that it does.(A lot of Gamecubes were sold thanks to this)

Halo-Pretty much the game that sold the Xbox, and popularized shooters on consoles. (Others might say it was Goldeneye, but Halo brought with it online multiplayer which was the real kicker)

Final Fantasy 7-Known as the game that sold the Playstation. It was a great JRPG for its time, and helped some of the SNES audience to leave.

Pokemon- An example of a concept executed brilliantly. The collection, the motto of training, forging bonds through trading, it's the perfect game for kids. (And then there's the metagame, Pokemon metagame is like Magic the gathering metagame which makes people continue playing) Buy for the concept, stay for the charm and depth. Your system IS your Pokedex.

Tetris-basically the Wii Sports of the time. Easy, accessible, addicting, apealled to young, old, male, female.

Super Mario 64-the first open world 3D game, first game to successfully show off 360 degree control and camera angles.

Grand Theft Auto 3-started the "do whatever the hell u want craze", who thought killing hookers and causing mayhem would be such a hit.
