Becoming an E-sports Player in a Parallel World

You have traveled to a parallel universe where everything is the same as Earth, except for the technology and corporations. RTS (Real-Time Strategy) games are just becoming popular here. However, in this parallel timeline, because personal computers never existed, the RTS genre didn't exist at all before the advent of "Undercurrent Battlefield". It wasn't until the invention of the neural interface that people could work or play games while sleeping. The increase in each person's work output led to rising unemployment, but because sleep time could also be used for gaming, the entertainment industry flourished, and the esports industry was born. You decide to use your Earth experience to become an esports star here.
