Games like OGame

People who leave OGame usually want the same four things somewhere else: a universe that keeps running while they are logged off, an alliance to run with, attacks that take real time to arrive, and nothing to install. Swarm MMO has all four. In almost every other respect it is a smaller and blunter game, and that is the honest summary.

Side by side

	OGame	Swarm MMO
Resources	Metal, crystal, deuterium, energy	Probes, and energy from suns
Build queue	Central to the game	None. Production is automatic
Production offline	Yes	Yes, 10 probes a minute at the top level
Fleet travel	Minutes to hours	Seconds, further across a galaxy border
Combat	Ship composition, rounds, debris	Larger swarm wins, remainder holds the planet
Alliances	Alliances with ranks	Clans with ranks and shared vision
End state	Endless	Collapse a galaxy's black hole
Session	Minutes, several times a day	Minutes, or automated between visits
Install	Browser	Browser

What is genuinely different

OGame's depth sits in preparation. You decide what to build, in what order, against which neighbour, and a raid is the payoff of a plan laid days earlier. Swarm MMO has none of that machinery. Every planet produces the same thing, every order is the same order, and the decisions are about where and when rather than what.

The other difference is the clock. A swarm lands in seconds, so a border can move while you watch. The slow clock is elsewhere: technology is bought with energy from suns you hold, runs to level 100, and a full run costs 33,835,000 energy, which is a goal measured in days. Crossing a galaxy border costs a share of the swarm that depends on the far side, up to all of it against a galaxy still in its first 3 days, so the map has real distance in it even though nothing travels for hours.

What Swarm MMO does not have

• No espionage. You can see what sits on a planet if it is in your vision; there are no probes to send for a report and nothing to hide.
• No fleet composition. There is one unit. A fight is decided by how many arrive, not by what they are.
• No research tree of that depth. Technologies are a handful of tracks bought with energy, not a lattice with prerequisites.
• No trade, market or expeditions. Nothing is bought from another player and there is nowhere to send a fleet except at something.
• No moons or debris fields. A destroyed swarm leaves nothing behind.

If those are the parts of OGame you liked, the closer alternatives are Hades' Star and Astro Empires, both of which keep the queues and the fleet detail. Swarm MMO is the wrong game for that itch and there is no point pretending otherwise.

What carries over

The habit that transfers best is border awareness. Planets changing colour near yours mean someone is expanding toward you, and the answer is the same as it always was: reinforce the ones you intend to hold and upgrade them. An upgrade costs 100 × level² probes, so 100 for level 2, 400 for level 3, 900 for level 4, up to level 10.

Clans work the way an alliance does. Members share vision, can reinforce each other's planets, and a galaxy counts as conquered when the clan between them holds every sun in it, which is what makes the black hole takeable.

Play costs nothing and needs no account, so the cheapest way to find out whether the trade suits you is about five minutes.
