A trend I see here a lot is that people tend to limit their games to what is available. With the 2 themes built in, it's just too much of a limit. Forget about what you already have and know. Here is a little piece of a paper I am working on. I hope it helps.
Quote: "What kind of game should I make?
In order to design and create a successful game, we need to know what makes a good game, and what players are looking for. Richard Rouse III, Design Director at Surreal Software said it this way;
"It may seem too simple a question to even ask, but determining what players want out of a game is a question all game designers must contemplate if they want to make great games. Further complicating matters, understanding what is enjoyable about a game experience is not knowledge that can be taught; on some level it must be an innate sense that a designer possesses. Designers must have the ability to assess whether something is fun for themselves, combined with the ability to listen to the opinions of others."
I especially like the last sentence. Basically, what is fun and exciting for you will be so for others as well. Why do you buy or play the games you play? While there is a probably a long list of reasons, I'm sure some of them will be:
A challenge
To Socialize
A Dynamic Solitary Experience
Bragging Rights
An Emotional Experience
To Explore
To Fantasize
To Interact
Whatever the reasons, you can bet others are buying and playing the games they do for some of the same ones. Just as a writer does his best work when writing about something familiar to him, so too will you do your best when designing a game that is fun and exciting for you.
Get it in writing.
The old adage concerning a guarantee is also good for game development. Once you have the idea in your head, it's time to get it on paper. How detailed and exacting you make your plan is up to you, but the more descriptive and detailed your plan, the easier you will find it to keep you game on tack and see it to completion."
Start with an idea, something you would both enjoy and know something about. Don't worry about the name, it will probably change as your story develops. If you do it right, by the time you get to the editor, you will be working from a book, and creating your world from the thought you put in it.
Best.
