Although I do love RTS, and adventure flash games...as well as some shooting games; anything that has to do with upgrading I certainly fell in love with. However, as I grew older...I believe I played them to the point where it is seems pointless, or not as appealing. I believe it would be a great introduction to many game sites to have mind challenging games for people who like to sharpen their mind once in a while. One game in particular which has been my favorite, on www.lumosity.com, is this game called RainDrops: Falling equations that you must punch in and enter before they fall into the bottom of the screen; harder and faster as you go. I believe this could be a great game to spin off of. It's a very simple, challenging, and competitive game. Yeah boring after a couple of times...but if you enjoy stimulation, you'll come running back to them sooner or later.
