What Game will do well ?

I am a bit frustrated i have to say.

I really want to have my Indie games be financially successful. The need and desire for this has several aspects to it. It is not just an avaricious thing like it could be. Though i know everyone wants to make oodles of money (of course).

1. I have a family to support so spending all my time developing Indies detracts from my family time. If the earning of money for the time i spent doing it, it would pay me back time elsewhere.

2. Making money is a side effect of making a game that is popular. I write games so people can appreciate my art, my skill, my creativity. I get a big thrill knowing that people are playing my game. Sometimes in the past I have received fan mail from games players and i can tell you first hand, that it is a wonderful feeling. I really want to see as many people as possible playing my games.

3. This games industry has become quite turbulent and seems to me to be getting more and more turbulent as time goes on. This means I fear for the permanency of my job now more than ever. Ever since THQ arbitrarily laid off everyone at Mass Media a couple of years ago i have had this slightly paranoid feeling of being on the edge of losing my job (yes i also work professionally in the games industry.

4. Independence.. I really want this. I want it because Interviewing for a job in ya late 40's sucks. Who wants to do that, i know i don't. Also having Independence will allow me to code most anywhere. I have been very fortunate in my 16 years over here in the USA to meet really nice people. A lot of these people i call good friends. Heck, my children and theirs have been growing up together.. or were, until they had to move to another state because of the job market here in southern Cali. I want to visit all these people spread across the USA, and i would love to do it over a whole kids school summer break. How fantastic would it be for me to go around the USA for 6-8 weeks towing my trailer and yet working at the same time. Freakin wonderful!!

Back to the main main title. My frustrated quandary.. And i am very sure i am not the only one in this situation.

I started work a few days ago on a bouncing game idea, and i love the way it feels already. But there is a lot of work involved in making this game because of the quality level i want and because of the number of levels etc. I tend to work on the level design and level feel as much as i do programming a whole game, I love balance in games.
Anyway i also have a strong idea for an RTS game, it has a design that seems to give it a unique but very accessible edge, so i wanna do that too. Only.. I can only write one game at a time. So how the Heck do i decide which game to write? Which is possibly gonna be more popular? Which is most likely to be more visible?

I have no answers so i am frustrated.....

Good luck to all you other devs trying to make this decision, I hope ya make the right call.
