What the Table Teaches You

The first decision in a building game is what the player is. Most of them answer "a god": you float above an infinite plane, the camera drops to whatever height you scroll to, and the world extends until the hardware complains.

Traluno answers differently. You are a person standing at the front edge of a wooden table, 3 m by 1.6 m, in a hobby room, and your eye is about 1.64 m off the floor, which is where it sits on someone about 1.75 metres tall. The layout is HO scale, 1:87, and the scales post sets that beside the others. The room has walls, a window and a door, and you stand on a rug on a plank floor.

That sounds like flavour. It is actually the constraint that settled a dozen later arguments before they started.

A table has edges, and edges are a design gift

An infinite plane has no composition. Every direction is the same direction, and the only way to make one part of the world matter more than another is to put something expensive in it.

A table has a front, a back and two sides. The front edge is where you stand, so it is the most-looked-at strip of the whole layout, which is exactly why the control desk lives there and not in a menu. The back edge is where the mountain goes, because a mountain at the back reads as distance and a mountain at the front reads as a wall. The corners are awkward, and awkward corners are a genuine puzzle for a player to solve rather than a bug to fix.

None of that had to be invented. It comes free with the table, and every real modeller already knows it.

Eye height decides what a building is for

Standing at the front edge, your eye is about 74 cm above the tabletop. In HO that is about sixty-five scale metres: you are looking down on a small town from the roof of a twenty-storey block.

At that angle you see roofs. You see roofs far more than you see walls, and almost never see a ground-floor door unless you deliberately crouch.

So roofs carry the detail: courses of cubes stepping up to a darker ridge cap, a chimney with a cap of its own, and a little colour jitter from cube to cube so that no roof reads as one flat sheet. Doors, door hoods and shopfronts are there too, but they are what you find when you go looking, and that is the honest answer to "how often will a player see this?"

The same logic runs the other way for vehicles. A car is small enough that from standing height you read its silhouette and nothing else. That is why road vehicles are smooth single shapes rather than stacks of cubes: at the size they occupy on screen, a voxelised car reads as a lump of scenery instead of a car. Two material languages is the longer version of that rule.

Scale makes the physics arguments short

Every "should this be possible?" question in a normal building game turns into a taste debate. In a model railway, HO scale answers most of them with a number.

Does track over water need a bridge? It gets one automatically: lay track across water and it becomes a deck on side girders, with a pier at each end of every cell. The reason is not that we decided bare rail looked bad. A cell is 10 cm, which is nearly nine scale metres, and nine metres of rail does not hang over water on nothing.

Can the mountain sit over the track? Yes, and it carves a tunnel bore with stone portals wherever it does, because that is what a mountain does to a railway. The mountain and the harbour crane are the only two things that can stand over track at all.

How tall can an overhead structure be before a train hits it? The tallest vehicle is the electric locomotive with its pantograph raised, 5.95 cm above the rail head, or about five scale metres. That is a measurement, not an opinion, and anything that spans a track is built to clear it. The harbour crane was braced at train height in its first version, the wagons drove through the bracing, and there was no debate about whether that was wrong; the loading gauge tells the story.

Constraints that come from the subject matter are the cheapest constraints you will ever get. Nobody has to defend them.

The room is not decoration

It would have been easy to render the table against a flat colour and call it done. The room earns its cost in two ways.

It gives the light somewhere to come from. The sun stands on the window side of the room and crosses it as the CLOCK lever on the desk runs the day forward, so the side of the layout facing the window is the lit side and the shadows fall towards you, the way shadows in a room fall. After dark the ceiling lamp takes over. A sky gradient with no room around it looks like a screensaver. The hobby room is the default, and a cellar, a pavilion in Bali and a garden can be chosen instead; the garden railway and the other rooms shows all four.

And it gives the layout a size. A table in a room is obviously a table: you can see how much floor it does not cover. The moment you buy a second table and the room gets tighter, the thing you have built acquires a scale you can feel. On an infinite plane, doubling the world changes nothing at all, because the world was never bounded to begin with.

What it costs

Honesty demands the other column. The table costs you the thing every infinite-plane game gets for free: unlimited room.

One table is 30 cells by 16, players run out of space, and running out of space feels bad. The answer, another table, is a real answer: $9.99 each with VAT included, up to four of them in a two-by-two block, as from one table to four lays out. It is also a paywall standing exactly where the fun was. A new layout costs nothing, but it is another table the same size, not a bigger one. That tension is not resolved, and pretending otherwise would be dishonest. It is the single sharpest edge in the whole design, and it exists because of the decision described above.

We think it is still the right trade. A bounded world you can fill is a world you can finish, and finishing something is a feeling an endless plane cannot give you.
