WarGames 2.0 is a text based, strategy game. WG2 is turn based, meaning you receive turns every 30 minutes of time that passes in the real world, which means it doesn't matter if you have 15 minutes or 15 hours of free time, you could play the game either way.
Every country in the game is an actual person. There are no computers; no fake countries, nothing. Everyone's real.
