Games Like Starter Pack

Is it possible to make the game with only starter pack content? I made the game in Unreal Engine 4 with only Starter Pack content.

It is an action open-world FPS RPG game.

You can loot chests. You can have different types of armor. You can level up. We have zones in the game. 20 zones. Melee mobs, range mobs. Trading system. Five different types of weapon: gun, fan gun, blaster, fan blaster, and EMP. Epic boss fights.
