I'm developing a facebook game, at the very beginning, my will is trying to launch the game asap, after a month coding, I finish 70% coding of my game, and the rest part are images, then 2 of my friend join in because they are interest, they suggest that we form a company together, me 60%, 40% is them, however, I think that it is not necessary to form a company at this moment, I plan if any success is forecast after 1 month of launching, then it would be nice to form a company rather then start at the very beginning.
But another problem is I don't know are there any trap or risk I need to notice if I do not form a company. Will it be difficult to migrate the new company details later, or anythings I will lose if I do not own a company, please help, thanks.
