Although I don't know when, and have learned not to make any promises, I would like to in the future make some in-depth and detailed AS3 tutorials that explain how to make a specific game type. I've noticed that it is pretty hard to find 'good tutorials' that explain many of the steps the are required to make a game - this forces many beginners to start off Flash with bad programming technique - which is no good in the long run. So, since I feel like I've become fairly familiar with game making I could help a lot of beginners by creating a good tutorial. So my question to you people is:
What kind of game would you like to learn how to make? What kind of games do the majority of people want to make? Obviously people on this site might look to make RPG's but there would also be a wide desire to make a platformer, shooter, tower defense, etc. So give me some feedback and let me know what you think.

Tower defence would be good I think.
It not only gives you the basics (button for towers, drag&drop, money handling etc.) but also trigonometry and auto aiming knowledge which you definitely will need for shooters.
