Games decided by the decision you made twenty minutes ago.
Strategy is the broadest category on the site, and the one where the online element changes the game most. A campaign against an AI can be solved. A match against a person cannot, they adapt, they bluff, and they punish the habit you did not know you had.
You will find two very different tempos here: the five-minute decision cycle of a MOBA teamfight, and the multi-month arc of a browser wargame where an alliance you negotiated with in March decides your April.
