Odd. Very odd.
As to apologise for the post I am about to write:
TL;DR and sorry for bumping.
I know I'm a few weeks late, but I'm not a regular reader (so I didn't read this when it was posted) and I read:-
"You remember my context-challenge-gratification triangle theory of game design, right?"
Well a few days ago, I had one of those 3 am brainwave things where you have to get up and put them down on paper, lest you forget the brilliant thought (As you would reckon at 3 am.)
So I drew this triangle thing, and here we are.
In my triangle, I originally put the big word FUN in the centre, and drew a triangle around it.
At each corner I place the words, but mine were different, sort of. I had CHALLENGE, STORY and ADVENTURE. It was pretty much the same thing as what Yahtzee was talking about (I think) only with more problems when I actually tried to plot games on it.
See, how my chart worked was each game was closer to a point depending on what part was done better in it, for example, Just Cause 2 was right on the point of adventure, with the huge sandbox where you can look up at a mountain and think, "I am going to climb that" and it will be so. Cave story is another example, where I thought it lay closest to story, the second closest adventure, and not completely dead for, but quite far from challenge. I defeated the Doctor because I wanted to see the ending, not because I wanted to defeat the Doctor.
Now those games did what they did well, but when I tried to plot some other games, they didn't seem to fit. Portal was one, Amnesia another, and so on. (Don't ask me why they didn't fit, again, I don't remember much about 3 am.) And bad games took the cake. I didn't actually plot any, but where would I put them? If a game failed on all three of these points, would I put it in the middle, in the fun zone? Would I put it outside the triangle?
Yeah, everything stopped making sense after that. 3.30 is bed time.
The idea Yahtzee had fills in the sleep deprived blanks I made and hadn't actually looked into fixing myself. In particular, replacing adventure with gratification and to a lesser extent replacing "FUN" with "How good the game is."
I haven't actually tried to plot any games on his chart, but this concept makes more sense than mine, and I could try reading the 50 odd comments of people who actually tried this, but hey... Who actually reads comments?
Also, I was reading xkcd comments before I came here. Did you know there are now a thousand of them? There are now a thousand of them.
