I kinda wanted to throw a game idea on the wall and see what stuck.
I guess a background is in order. I'm 43 and have played nearly every MMO since Merdian59. And honestly year after year MMOs are get worse and more basic.
What I am proposing is a stratergy type mmo. IE. Wizard101 for adults.
I think a casual stratergy game is a much needed genre.
It's good to have some ideas from playing games, but it sounds like you don't have a lot of experience on the development side. The most common mistake is to choose too large a game with too much scope. MMO's are generally the hardest games to produce and have a very high failure rate.
