One Big Game Server or Two Small Ones: Which Costs Less?

On hosts that price by RAM, two small servers cost about the same as one big server with the same total memory, so the price is rarely the deciding factor. What decides it is overhead and CPU: every server process carries its own base memory use, and two servers on separate plans each get their own CPU share instead of fighting over one. If your group only plays one game at a time, the cheapest option is neither: keep one server and switch it between games as your group moves on.

Here is how to work out which setup fits your group, with the math for common cases.

The three options

Option	What it is	Best for
One server per game or world	Separate plans, each sized for its job	Groups that play two games in the same weeks
One big server running everything	A VPS or large machine with several servers on it	People comfortable running their own machine
One server you switch between games	One plan, one game at a time	Groups that play one game at a time

Why two small can cost the same as one big

At per GB pricing, the math is linear:

2 GB + 4 GB = 6 GB of RAM in total
4.99 + 9.99 = 14.98 USD a month
one 6 GB plan = 14.99 USD a month

The total is almost identical. So the question is not price, it is what you get for it.

Overhead: every server pays a base cost

Each running game server uses some memory just to exist: the game engine, its libraries, Java's runtime for Minecraft, the loaded spawn area. Two servers pay that twice. So two separate 4 GB servers each have a little less usable memory than half of an 8 GB machine running both. On a light game like Minecraft or Terraria, that overhead is small. On heavy Unreal Engine games like Palworld or ARK, the base is large: each of those servers needs a lot of memory before anyone joins.

CPU: where separate servers win

Game servers do most of their work on one main thread. Two servers on one shared machine compete for CPU time, especially at the same moments, like an evening when both groups are on. Separate plans each come with their own CPU allocation. If one server has a lag spike, the other does not feel it.

Running two games on one VPS

If you rent a VPS or use your own machine, you can run several game servers side by side. It is flexible and can be cheap per GB, but:

You install, update and back up each one yourself.
You set ports so they do not collide, such as 25565 for Minecraft and 2456 to 2457 for Valheim.
One crashing server or runaway memory leak can starve the other.
You manage the operating system and firewall.

Two worlds of the same game

Minecraft

You can run several worlds on one Paper server with a plugin such as Multiverse, so one 4 GB server can hold a survival world, a creative world and a minigame map. That shares overhead and costs one plan. The trade off is that everything shares one main thread, so a laggy farm in survival slows down creative too. Separate servers keep them independent.

Valheim, Palworld, Enshrouded

These games run one world per server. Two worlds means two servers. Valheim worlds can be swapped by changing the world name in settings, so one server can hold two saves and run whichever one the group wants this week.

Switching games on one plan

Most friend groups play one game hard for a few weeks, then move on. Paying for two servers when only one gets played is the most common way groups waste money. Better options:

Keep one server and switch games when the group moves on, on a host that supports it.
Keep the old world as a download so you can come back. See how to download your world.
Only run two servers in the weeks you really play both.

Our guide on one game server for multiple games explains how switching works.

Worked examples

A Minecraft survival world plus a creative world for 6 friends. One 4 GB Paper server with Multiverse is enough. Cost: 9.99 USD a month instead of two plans.

Valheim on weekends, Minecraft on weeknights, same group. Two separate servers (Valheim 4 GB, Minecraft 2 GB) cost 14.98 USD a month and never get in each other's way. One 6 GB VPS could run both for a similar price, with more setup.

A group that just moved from Palworld to Enshrouded. Do not pay for both. Back up the Palworld world, download it, and switch the server to Enshrouded on a plan of the same size.

A Discord community with two different groups playing at the same time. Separate servers, so one group's lag never hits the other.

How it works on GamezServers

GamezServers runs one game per server, and each server is its own plan and subscription, so two games side by side means two servers, each sized for its game. Both appear on your dashboard, and each can be split with a different group of friends. When your group moves from one game to another, open Settings and switch the server to another game with a plan of the same memory. We back up the current world first, and your price only changes if the new plan costs more or less. If you delete a game but keep paying, the server becomes an empty slot you can start any game with the same memory in. See the multi game server hosting page or the control panel docs.

FAQ

Can I run two games on one game server plan?

On most managed hosts, one plan runs one game at a time. You can switch between games, or run two plans. On a VPS you can run several servers on one machine.

Is one 8 GB server cheaper than two 4 GB servers?

At per GB pricing they cost about the same. Two servers each pay some memory overhead, but each also gets its own CPU share.

Can one Minecraft server have several worlds?

Yes, with a multiworld plugin like Multiverse on Paper. They share one server's memory and main thread.

What is the cheapest way to play two games with the same group?

If you play them in different weeks, one server you switch between games. If you play both every week, two servers each sized for its game.
