### Does the computer cheat?
No. The AI nations pay exactly what you pay and only know what they have scouted. Rival alliances have a war council that picks targets, signs pacts, scouts and strikes together, but always with the same rules as you.

### How long is a game?
You choose: a Quick season of 200 turns, Standard of 400 turns or Epic of 840 turns. It is turn-based, so you can end each turn yourself, or let it run automatically at 1x, 5x or 20x speed. Difficulty is Recruit, Veteran or Warlord.

### Is there multiplayer?
Not yet. What you play now is Season 0: single-player against AI nations, the training ground for the live world. The live world, one shared season with real people as the other nations, opens when 100 commanders have joined the waitlist on the Terrastate Discord.

### What is Season 0?

### What is Romaterra?
Romaterra is the same game set in the age of Rome. You gather denarii, grain, timber, iron, livestock and bronze, train legionaries, cataphracts, ballistae and war elephants, and fight to take Roma and hold the Imperial Palace.

### What games is Terrastate like?
Terrastate is inspired by tick-based browser strategy games such as Planetarion, with the alliances, scouting and timed attacks of that genre, plus the map and diplomacy of a grand strategy or 4X game. The difference: you play against hundreds of AI nations, at your own pace, without waiting for other players.
