It would be hard to walk away from something you have worked hard on for years. Im not sure if you have commited yourself to something which has taken years of dedication to produce and be so easy to walk away from. These guys were already pretty wealthy, to me its personal to them to see the game going from bad to worse.
if that is the case then why leave, why not fight for your "baby" to develop into something better. Seems like they took the cowardly way out.
If they were so committed to the company then why hand it over to EA? the new that EA would give them a shed load for their company and they selfishly took it and ran.
The Word "commit" is a dead word in today's society.
