Well, let me know if you ever raise a bunch of capital and start a successful company. I will come work for you, gain a bunch of "experience", and re-create your company on the side. When I get the "atta boy" from you, I will move on.
I created an account here just to comment on this. I am not aware of the whole story here, specifically if he did the game development on his own time (i.e. while not at work). However, I employ several software developers for the development and maintenance of a billing system which we deploy using a SaaS model. I would be very upset, and would in fact view it as fraudulent activity, if one of those developers built a competing product, especially while they were at work and I was paying them to do work for me. And, even if the developer did all the work at home, I would still have IP concerns. How would I know he was not ripping off a bunch of ideas or code from work?
I know that hackers are a fiercely independent lot, as I am myself, which is why I started my own company. However, we have to be careful that we don’t go too far with the “stick it to the man” attitude. Put your self in the employer’s shoes. What if you started a company, put in a bunch of money and time, only to find out that one of the people you hired was developing a product very similar to yours on the side. How would you feel about that?
