What's most important in a good game？

[c-bob]

Depending on what type of game aside i would say immersion is the main thing for me.

Immersion, Graphics, Gameplay.. kind of all in a good mix.

Atmosphere. That's why I love Red Alert 1.

[djnemonic]

Gameplay, replay value, originality, quality, story, amongst many other things.

Gameplay and story for me I'd say. If one of these two is not up to par, there is a big chance I won't be able to even finish the game.
