I just set records in both design and tech. Put out an RPG with a new topic, new combo, that was great, and received a good management bonus. Somehow I scored only two 7s, a 5 and a 6. What is wrong with the scoring system? I used that stupid wiki, but now that I have 4 staff members it doesn’t really help. The scoring system makes no sense. I thought it was just the - categories that double punish the player, but now I have no idea why I get the scores that I do. I usually release good games, but inexplicable duds seem to drop, that should be my best games.
Maybe the problem is competing against your last top score vs an industry standard for each genre…
The next incarnation of this game needs to simulate other companies that you are competing against so that scores are not so arbitrary. The score of my RPG should be based on how my games design and tech points match up with the scores of other recently released RPGs.
"Got it? Your strategy is to improve your Game Score every time, but to improve it by minimal amount you need to get another good review, never improve it too much. The true skill and true goal in this game is not to release AWESOME games with all the cool stuff you can cram in, but to calculate carefully and always release games just exactly enough better in order to get another ~9 review. "
I’d say that this, and the - categories are what is wrong with the games’ scoring system.
As long as you are ahead of your competition, your scores should be the best, and you should sell the most games. Marginally out scoring your last game should not be the goal, unless you want to encourage players to make Madden-like garbage.
You have to achieve a good tech/design ratio also. With RPG’s the Tech should be roughly 60% of the design, so for example if your RPG is 100 Design, your tech should be about 60. if you go more than 25% away from this, you will be penalized in your score.
You will also lose score on your game if your sliders are set to incorrectly for that genre.
So Tech can be too high… That’s the problem.
If my design is better than the other guys, then the better tech is just a bonus.
It shouldn’t be held against me that my RPG has great AI… it would be an improvement over the brain dead AI that occupy most RPG games.
Sadly that is not how it works. I have pointed that out lately in another post (somewhere here). If you try to make current games like Mass Effect you will most definetely fail. These games must be good in all of the 9 categories. But in reality you can’t create AAA games with 7 people either. 
The researched technologies for the current console generation do also matter heavily, as far as I can tell. Was struggling with a bad engine in my last playthrough and had a really hard time with the new consoles.
