The only thing stopping you guys from having a development team is you. Advertise in the Hobby Section of the classifieds on this site. Oh Yea, thats right, everyone wants to get paid, everyone is afraid of someone else stealing their work <( Intentienal Sarcasm ). If that is the case then develop a contributer's Agreement, where everybody has a shared copy of all the work and a cash agreement if it goes to Market.
What are the different ways for finding new game concepts?
Your Brain contains the Best Program Ever Written : Manage Your Data Wisely !!
The most important search is inside of you. Your imagination has far more potential to inspire both you and others than any external source filtered thru you.
Personal life and your private thoughts always effect your career. Research is the intellectual backbone of game development and the first order. Version Control is crucial for full management of applications and software. The better the workflow pipeline, then the greater the potential output for a quality game. Completing projects is the last but finest order.
