"A game is an interactive structure of endogenous meaning that requires players to struggle towards goals"

I personally like the way he says struggle instead of something like challenge. Surely it is the challenge of a game that keeps us playing, at least that's why I keep playing. I Can understand why would you play a game just for fun, but surely there is some kind of challenge within. Me personally, I like the challenge.

We all start out wanting to play/complete or be the best at a game. But the struggle must be the journey the player takes. Its like a cheesy movie where a group of friends set out to go somewhere, but then when they get there (although it could be amazing) realise that the journey means more to them. I remember completing Mass Effect 3 and the bad comments the ending received about how it should of been better, but i didn't care about how 'bad' it was. I remembered what an awesome time I had had playing the game, I remembered how the struggle of the game made me feel. It wasn't about the objectives, although I was trying to complete them, it was about how I was completing them. 

When he says they are endogenous I agree with him. He says that "games are fantasy" which I also agree with. If I went around saying I was the king in some game, people that don't play the game (or are not in that fantasy), won't care and would probably think I was crazy. But someone in the fantasy would treat me as royalty. To me this is the true understanding of a game.
