How we scored — open methodology
Compiled by the Xterium team. The methodology is open, scores are argued; where a competitor is stronger, we say so directly. Six criteria, 1–10 points each:
- Accessibility — browser without install? mobile apps? entry cost
- Monetization fairness — can power be bought; are the formulas open
- Strategic depth — economy, research, empire scale
- Team play — alliances: wars, roles, joint actions
- Respect for your time — can you play 15–30 min a day without losses
- Project liveliness — updates, community (verifiable)
Scores marked "by player reviews" or "by genre design" are argued judgements, not measurements. Store ratings and update dates were taken from store pages and official sites on 2026-07-17 — they change over time.

FAQ
What is the best browser online strategy game in 2026?
Among games with a full browser version, the top scores in our table go to Xterium: War of Alliances (48/60 — browser + iOS/Android with one account), Forge of Empires (42/60 — the living classic of browser strategy) and, tied at 39/60, Travian: Legends and Conflict of Nations: WW3. EVE Online (40/60) scores higher than both, but plays only via a PC client.
What is the best mobile space strategy game?
The most time-respecting one is Hades' Star: DARK NEBULA (async design built for 2–3 short sessions a day). The EVE sandbox in your pocket is EVE Echoes. Xterium fits if you want one account in the browser and on the phone: native iOS/Android apps with auto-sync.
What is the best free strategy game without harsh pay-to-win?
All 18 games in this ranking are free-to-play — the difference is monetization fairness. Our highest scores went to Xterium (7/10 — open formulas and identical combat stats for paying and free players, though loot boxes do exist) and Hades' Star (7/10 — by player reviews, comfortable without paying). The lowest went to Xcraft and Goodgame Empire (3/10 — persistent pay-pressure complaints in reviews).
Why is Xterium first? It is your own ranking.
Yes, the ranking is compiled by the Xterium team — that is exactly why the methodology is open. Xterium totals 48/60 because 3 of the 6 criteria (accessibility, respect for time, team play) are precisely what the game was designed for. The weak spots are stated directly: liveliness 6/10 (the community is many times smaller than the giants), depth 8/10 (EVE Online got 10), monetization 7/10 (loot boxes exist). Disagree with a score — every cell in the table carries its argument.
Where does the data come from and how often is the ranking updated?
Store ratings and update dates were taken from app store pages and official sites on 2026-07-17; they change over time. Scores marked "by player reviews" or "by genre design" are argued judgements, not measurements. The ranking is updated quarterly.
