Hi Xenxander,

The thing you need to realize about the charts on the "Game Development" page is that they are calculated based on thte raw data in the game, and then simplified to + and - for people who don't want to dewlve into the details of "Raw Data" and "Review Algorithm". In the game code, it's not as simple as + and - so when you try to derive the multi-genre chart from the simplified single-genre chart, the result is not correct.

I'll use your example of Action/Adventure and Simulation/RPG to show you how to calculate. If you lookup the "Development Focus" chart on the Raw Data page, you can see the engine focus for those 4 genres are 1, 0.7, 0.9, 0.7, respectively. So the engine focus for the Action/Adventure combo is 1 * 2/3 + 0.7 * 1/3 = 0.9 and for Simulation/RPG it's 0.9 * 2/3 + 0.7 * 1/3 = 0.833.

Now, the game use the focus number like this: if it's greater than or equal to 0.9, it's important (+). If it's between 0.9 and 0.8, it's neutral (~). If it's less than 0.8, it's unimportant (-). When you apply this rule to the two numbers calculated above, you get Action/Adventure's 0.9 is important (+) and Simulation/RPG's 0.833 is neutral (~).

Hope this answers your question.
