CD Projekt Red has published a fact sheet about themselves which highlights not only their business but also the global potential of the gaming industry. They show the distribution of their revenues and a total of 87% comes from Europe and the US. Only 8% come from Asia & Russia and 5% from the rest of the world. I am pretty ceratin this is representive of most AAA-games today.
There is no reason that The Northern Kingdoms, the land in which The Witcher takes place, could not be located on the screens of Asians, Russians, Africans or South Americans. Especially as The Witcher is rated the world's best RPG.
One of the main reasons for the global imbalance of The Witcher revenues is access to computer power. We can see this represented by the fact that CrossFire is the most played game in the world - a free-to-play game which requires very little in terms of computational power. A lot of Asian gamers are still playing games at internet cafes, as many don't have home access to gaming rigs. One of the big advantages CrossFire has is that it’ll run smoothly on basically anything.
Looking into the future, there are few things that I can think of that are as correlated to GDP growth as access to technology. Thus, as economies grow and move forward more people will have access to gaming, both in terms of time and technology.
As the world outside of Europe and US continue to grow so will their share of global gaming revenue - and the map above illustrates how huge the potential is, with at least a 5x fold growth potential globally. So if you want exposure to global growth, one pure play is being exposed to the AAA-gaming sector.
