Exploring buys new land with gold and soldiers. It is the peaceful way to grow, and it gets dearer the bigger you are. Each acre also spends one of your explorable acres.
- Gold: 300 an acre, plus 0.75 for every acre you already have, plus a part that grows with the square of your land beyond 1,400 acres (doubling that extra land roughly quadruples it), times your explore cost modifier. However many cuts stack, exploring never costs less than 25% of the base gold.
- Soldiers: 0.005 for every acre you already have, plus a part growing with the square of your land likewise, per acre explored (rounded up over the order). They settle the land and don't come back. See the draft.
- For example, 400 acres: 600 gold and 2 soldiers an acre; 1,000 acres: 1,050 gold and 5 soldiers an acre; 2,000 acres: 1,890 gold and 10.36 soldiers an acre; 4,000 acres: 4,990 gold and 26.76 soldiers an acre.
- From 1 to 1,000 acres at a time.
- The land arrives exactly 12 ticks later. Until then it shows as incoming land.
- Races with no_explore can't explore and must grow by attacking.
Explorable acres
You can only explore as many acres as you have explorable acres. They grow every tick by a share of your land: 0.75% of it while you have 400 acres or fewer, falling along a curve to 0.02% at 6,000 acres. The curve drops quickly at first and then levels off, so a growing house soon explores at a steady pace rather than in bursts.
The gain is also capped in acres a tick. A bigger house never gets more than a house of 400 acres. Past 6,000 acres the gain stops growing: every house that size or bigger gets the same acres a tick as a house of exactly 6,000 acres.
They bank up to 48 ticks' worth (2 days); beyond that they stop growing until you explore. A new house starts with a full bank. For example, 400 acres: 3 a tick, up to 144 banked; 2,000 acres: 3 a tick, up to 144 banked; 3,500 acres: 3 a tick, up to 144 banked; 5,000 acres: 2.2 a tick, up to 103 banked; 6,000 acres: 1.2 a tick, up to 57 banked.
You can send explorable acres to a house of your state as aid, to help it grow faster.
While your state is at war, explorable acres grow at 12.5% of the usual rate, and exploring costs 400% of the usual gold and soldiers.
