Three newcomers join the catalogue at once: **[OpenTTD](https://tickserv.com/games/openttd)**,
**[Avorion](https://tickserv.com/games/avorion)** and **[Necesse](https://tickserv.com/games/necesse)**. They have little in common, other
than being games you pick up in waves — exactly the shape where paying a monthly plan for twelve
hours of play makes no sense.

## OpenTTD, the lightest server we know how to run

The railway-and-truck network game, open source for twenty years. A server takes **8 players by
default, up to 25**, and sits in **25 MiB of memory** at rest — measured on the image we serve, and by
far the lightest of our games.

Three choices are locked when the map is generated, because the game can neither grow it nor change
its climate: the size (up to 1024 × 1024), the landscape and the starting year.

## Avorion, a galaxy that goes on without you

Ship building, trade and exploration in a procedural galaxy. **4 players by default, up to 10.** The
galaxy seed is locked at creation; everything else — player-to-player damage, same starting sector,
infinite resources, collision damage — can be changed whenever you like. The game is baked into the
image: nothing to download at start-up.

## Necesse, ready in seven seconds

Top-down co-op survival and building. **8 players by default, up to 20**, a console with kick and ban,
and an automatic save **about every minute** with a backup copy. On our test bench, the server was
ready in seven seconds.

## We ran the images before selling them

Our first acceptance run failed on a single point: on the second start, Necesse announced it had
created a brand-new world. Looking for the reason, we launched all three locally — and each one
surfaced a defect that reading the files had not. Seven fixes, two of which the acceptance run itself
could not have caught:

- **OpenTTD was running with no password.** Since version 14, the game splits its configuration across
  three files, and only opens the one holding the password **if the first declares its ini version**.
  Without that line: a server open to anyone who knows the address, without a word. The run checked
  that the interface handed you your password — not that the game applied it.
- **Necesse's world was not where we had put it.** The game writes `saves/worlds/<name>.zip`, with an
  intermediate folder that appears nowhere in its documentation. Our import was looking for a file
  that did not exist.

The other five: data folder ownership (OpenTTD wrote absolutely nothing, so no save at all), two
player-counting patterns that would never have counted anyone — both games timestamp their console
lines —, Avorion's version read in the wrong place, and the **empty** name that granted owner rights
on a Necesse server.

All three then passed acceptance on real machines, end to end: creation, start, connection address,
password, settings, shutdown, **second start on a restored world**, deletion, and the provider's
inventory back to zero.

## One guide per game, in three languages

Each has its full guide: [OpenTTD](https://tickserv.com/guides/openttd-server-hosting),
[Avorion](https://tickserv.com/guides/avorion-server-hosting) and [Necesse](https://tickserv.com/guides/necesse-server-hosting) — what gets
locked in, how to join, the RAM we recommend, and how to bring over a game you have already started.

## What this doesn't solve

All three servers are **vanilla**: no mod upload, and no NewGRF for OpenTTD. There is no console for
OpenTTD or Avorion either — their admin protocols are not the ones we speak elsewhere, and we would
rather not open a door we do not control.

Finally, the RAM we recommend for Avorion (8 GB) comes from two hosting providers' technical pages,
not from our own measurement. We will replace it as soon as a real play session gives us ours — that
is the rule we apply everywhere else, so we may as well say it here.
