elafreat Now I am confused, you asked him how you would sell it if it were an HTML5 game, then when he answered you said you don't intend to sell it...
HTML5 games can be sold to publishers looking to put it on their site,they can also be packaged as apps for windows, windows phone, android and apple...
With these even if the game is free to play you can put ads in it. Depending on the ads and the marketplace they pay you usually per every so many thousand impressions or clicks. But you still have to pay to get on those marketplaces and that is usually $100 for a year. Or I believe $50 a year for Windows Phone.
On the other hand profit sharing usually means you and some others get together to work on it and depending on what each persons role is you get paid a percentage of the revenue once the app begins generating money. It doesn't always work out that well so I would make sure if you are going to do it that you hook up with a good team that knows what they are doing and are not just messing around with high hopes. It takes some dedication and skill to get a money making game out there. Too many people are just throwing crap out there by the ton trying to get enough people fooled into downloading it that they can make some money. The upside to that is if you do put the time and effort in your game can still stand out from the sea of sub-par poorly design crap that is flooding the marketplaces. Just my 2 cents...
Hope this helps.
