I am doing research about games and game balance. The results will be published on my GDC Europe 2014 talk titled "Fun or Frustration: Game Balance Pitfalls and Recipes". I will also make them available online (also here on my Gamasutra blog).
With this research I will try to answer a few game balance questions such as preferred diffuculty levels in different age groups and game genres.
If you are a gamer and heve about 2 spare minutes, please help. I need a lot of responses to make the research valid.
Here is the survey link: http://bit.ly/1n3cjXs
I will be greatefull for sharing it with your friends. The more responses, the better the results.
