You might sell games, but then there is a problem of distribution (you must if you want to sell off-the-shelf games, or if the online option caters for you better). Then there is such a thing called “piracy”, or illegal distribution of games. Combating it is very costly.

But I suppose you need money. Then there is the gaming-as-a-service model. Just look at the likes of “Second Life”. The game client is FOSS (free and open source software). And you can connect to servers also for free. But the company behind “Second Life” generates huge money. How? The catch is paid services – offering players to buy “virtual real estate”, “clothes”, etc.

So, what matters most is the business model, not the marketing. Why, of course, market research is important, but to start business, you must have an extensive idea how _you_ will get money.
