Review Detail of ThePhinixKing in The Legendary Mechanic

The MC is 'trapped' inside that world. However it's uncertain whether or not it's truly a game world since it operates like a real world but to answer your question. Yes, the MC is Stuck in a game world.

I read a bit his playing before the beta comes out. so that means other real players will join him.? Thanks for the answers

yes the players join him after a few years and he ends up guiding them and using them to help him level up as an npc. He sells them things in exchange for thier experience so he can use others to level fast. You get to know a few of his player followers in the beginning but as he gets stronger and stronger it focuses less and less on the players because they are absent for long periods(10-50years) during verion updates.
