Business Wars — About this game
``Business Wars'' is not a management simulation where you freely decide product prices, but a command-choice adventure about the acquisition of an airline company and conflicts between companies. Through repeated conversations and research, you gather information from partner companies and related parties, and choose the appropriate actions for each situation to advance the story in all five chapters. It's important to not just brute force the commands that appear, but to remember who you asked what, and where you got new information. If you can't find more options, look again at the previous person or place.
