Do you think if you had a team of about 10 people all extreamly good in thier own skills of building a game(they are not profesionals though) Do you think it would be easy to put your game on the market if you had a good/original idea and good graphics?

You''d have to find a company to publish it. I''m not sure
how willing they would be if they knew it was done by a
group of people, not a company. Then again you might have
a really kick arse game and knock their socks off. It would take a bit of money as well to get it underway, not to mention the fact that the publisher would take a sizeable amount of the profits from your game.
But if the game''s good enough, go for it!
