What was your first game you loved?

That was an atari game about giana sisters and another atari game about montezuma's revenge.
Then there were many zx-spectrum games I really liked, like Dizzy 1-4, Thunderbirds 1-4, Exolon and so on.
And my first fav pc games were Doom 1/2, Warlords 1/2, Wolfenstein 3d etc.
