lets not get off topic.Now I think that by getting a site to sponsor your game you can make a good profit out of it.If you haven't noticed by now every game that is submitted on here has a sponsor,such as AG,Newgrounds,and tons of others.I think you have to use the contact page,and make a business proposal to get it sponsored,and then they should be the ones who pay you,but I could be wrong.Anyways that is the main way to get profit.If you are looking for even more,and have a really nice game.Then you can put adds within the game,and such which would help get more cash,but overall I think sponsors are the ones that help you make the most profit,and it could help make up for the money you spend on flash programs,and really nice computers to make the games on.
