How many PHP developers do you need to develop a successful PHP facebook game w/o graphics (such as mafia wars,etc). And is it that hard so i need dozens of super duper experts ? and how much should each earn per month(fixed or percentage).
sorry i have not much thing about mafia wars but generally a small team of 4-5 programmers can handle a good game for FB but if its flash, the interaction would need you some with a good flash end knowledge plus some php
This depends on your budget. If you have say USD 1k budget you can get it developed by somebody and pay him some fixed amount but if you have no budget you may have to share the profit if he agrees to. There cannot be a general rule like you have to be doing this only.
