Ok. I have your attention. You guys are the experienced developers. You say it takes a lot of people and experience to make a game. I believe you. But when I look at the game it looks easy to me to make. If honestly it does take a lot of people and a lot of time I'll drop it. But I'll explain again.
I use a wallpaper for the kingdom. Designate spots for you to build buildings. I need visual art work for each building. 20 buildings. All the game mechanics are done. All it needs is coding. World map is a plain flat surface with resources to gather, kingdoms of other players and monsters to hunt. Can it really be that hard and time consuming? If I were to draw on paper and use things on papaer I can make the game on paper in 40 hours or less. Why does it make it so much harder to do on the programming side? You all make it sound like I'm building a hard game. Its not like star craft, wow, lol, charter. Those are hard games. No story. No videos. The game mechanics are finished. Can it really be that hard? combat system like chess with 7 units. That's all. U ether move or attack or skip turn. No spells. Turn based. It really can't be that difficult. I could careless for 3d high quality graphics right now. 2d pixel art is fine. 2d in general art is fine. It doesn't need to high quality graphics. Look at mine craft. Candy crush. Simple stupid graphics. Even angry birds. I don't need 3d amazing animation.
So I use unity and gimp. Any other programs I need?
You probably want something to record and mix sound and music as well. (Audacity is free and probably good enough to start with).
And yes, it can really be quite hard, the biggest challenge for you will most likely be to prevent rampant cheating while still keeping the server side scalable and fast. Doing one of those things is reasonably easy if you know what you are doing, doing both at the same time is extremely difficult, The client side programming of those games is fairly straight forward but you still want some high quality artwork (which is both time consuming and difficult to produce)
