Aren's been a very prolific builder, with extremely fine details in many of his/her buildings. Many of them are placed inside the buildings, so it's hard to capture them if not on video - for example the castle holds many intriguing details within its walls. Here's an example of creative melding of multiple lots together; the castle is to the top-left, flawlessly connects to a stone quarry in the middle segment, with a bridge leading to the sawmill to the right. All of them built with fine details allowing 1st person walker mode exploration:
To give some point of reference, since this is an economy based game, Aren's castle shown in Syksy's post above cost:
- Land: 34.3 gold
- Materials: 11.3k sandstone, 30k pine, 210k labour. At full price, this sets you back about 182 gold
Total: about 216 gold
This building currently gets an income of 66 gold per tick (4 times a day) against a puny land tax of about 0.05 gold.
It really is a no brainer as the castle pays itself back in less than a single day. Of course, this is because there's very few players so far, which means the treasury emission gets shared among those very few people. When mainnet starts, we expect people to join early so they can share in the bounty too.
The stonecutter adjacent to the castle cost:
- Land: 30.6 gold
- Materials: 23.5k sandstone, 23.5k pine, 282k labour, so about 442 gold at full price
Total: about 473 gold
The stonecutter does not get automatic income as the castle does. Instead, it produces stone blocks, which you can use to build your other buildings cheaper, or sell to others, undercutting the full price supply. This particular stonecutter gets you 738 sandstone per tick (4.4 gold), using up 306 pine and 3.8k labour (1.83 gold), leaving you with a 2.57 profit per tick (assuming same price as above). A lot less than the castle, right ? But this production stays constant, while the income from the castle will go down as more people join the game, get building and start sharing in the treasury emission.
Now, this is a bit more complex than that, I did not count costs of food and heating material, and this is something you should get familiar with on testnet while there is still time before mainnet launch.
