How are we defining classic here?
If by games that had tremendous impact on gameplay, it's defenitely Zelda, Orcarina of Time
Hands down.
If by classic you mean 8-bit or less, then, uh...
Legend of Zelda.
Yeah.
And if we're talking about Atari games or games where the goal is to get points, then I'd go with Jetpack, a lesser-known old video game.
You think Pacman is intense? This game will rape you.
