I noticed certain developers pop out quality games like mad. Maybe they just have man power? Maybe they are just really really good at what they do. I just find it amazing. The coding, the animations, cut scenes ect.
Here is what they really do: spend about 10 years of their lives coding flash games. Officially announce the company and release one game. Wait a bit while coding more. Release another. Wait a bit while coding more. Release another. And so on.
