It seems to me that starting a career in such an industry is quite difficult, since there is a lot of competition. In addition, there are many different specialists that are needed in this industry.

And besides, you don’t need to be a specialist to start making money from this. For example, you can implement your projects with https://arrible.com/services/mmorpg-game-development/ and get a good result that will be popular among players.
