Ludo Lingo 2

I played I wish I were the moon yesterday and I have to say I didn't see any game in this.
Later that day, I came to think about what then constitutes a(n interesting) game to me, and why 'Moon didn't have it.

This is what I came up with:

A game isn't a game when it has interaction.
If all you do is press a button and a picture appears, that's interaction, but that isn't a game.

A game isn't a game when it has choice.
If you can go left and right, that's a clear choice, hell, you can even stand still. Doesn't make it a game though, moving my cursor isn't playing a game.

A game isn't a game if it has consequence.
This is a tricky one, since this statement would appear at first glance to be untrue. If the consequence is death aka reset it is false consequence.
you should be able to improve your current situation, position, state or abilities by your actions and their consequences.

Why I don't think 'Moon is a game: because you're not changing anything, you simply put the right object in the right place and watch the animation to find the endings.
I see no point in hunting for all the different endings.
I was so dissapointed when I saw a 1 min clip basicly showing the entire game played out before me I didn't need to play it anymore(though I did).

I had the same pondering over the game The Marriage by Rod Humble,  it too being of little consequence. Taking away its title, it would simply be 2 blocks, one pink, one blue, one growing larger when a mouse is put over it, the other being attracted to the first. The title forces the "meaning" onto it, it is not communicating much meaning through the actions or mechanics. You're not improving or progressing, you're just watching the immediate reaction of the 2 blocks to your cursor.

I think that what I keep looking for, is for the game to somehow dare the player to undertake an action, and that action not just having a direct consequence like showing an animation or an object changing direction, but actually have the effects have a more substantial influence over how the rest of the game plays out. 

Tetris comes to mind, as with every piece you position, you evolve the puzzle as you go.
