Big-O .Inc
Big-O .Inc follows Emily Harris as she takes over a neurotransmitter production facility. Running the business gives you production figures to watch, staff to hire, and research to oversee, while conversations and emails develop her adult workplace story. The presentation is mostly text, with the writing carrying the characters and their interactions. It's a largely linear experience, so you can follow along without worrying about finding a particular relationship route or getting every answer right.
The management is straightforward once you've learned where everything lives in the interface, though the opening could explain those screens better. Much of the routine involves waiting for output to increase, making the next conversation a welcome break. Some dialogue runs long, and a few character threads could use more follow-through. Your chosen tone also doesn't always carry into Emily's later replies. Still, if you enjoy reading a substantial story with a simple incremental game running around it, Big-O .Inc gives you a different kind of adult game to spend time with. The writing needs to be what brings you here.
