Warfront
Warfront is the sharpest head-to-head on this list. Recruit seven unit types locked in a rock-paper-scissors chain — spearmen skewer cavalry, cavalry runs down archers, gryphons hunt the skies — while your economy grows from every village you hold. A killable hero commander carries a one-turn power spike that can swing a losing fight. Win by holding the central Watchtower for four rounds straight, or by taking out the enemy's hero and headquarters. Damage is fully deterministic: no dice anywhere, so every loss is a planning lesson, not bad luck. Six maps, 2–4 players, free-for-all or 2v2.
Naval Battle
Naval Battle takes the classic hidden-fleet duel and gives it real tactics. Deploy your ships on a foggy grid, maneuver them into position, and fire based on ship type — a destroyer's spread differs completely from a submarine's single deep strike. Every hull carries one signature ability: a submarine leaves a lasting sonar contact, a carrier calls in a wide air strike. Reading the pattern your opponent leaves behind is the whole game. Strictly 1v1, and a full match rarely runs past ten minutes.
Estates
Estates is the pick for a longer, more social evening. Choose from five real-geography boards — a world map, or a focused layout for Europe, the US, Turkey or Asia — buy up city groups, build houses and hotels, and multiply the rent you charge. Live auctions and out-of-turn trade offers turn every stretch of bad luck into a negotiation instead of a dead end, and going bankrupt opens an auction of your own instead of ending your game outright. 2–6 players, nobody is eliminated early.
Seven Sails
Seven Sails puts economy and naval combat on the same tile-gridded sea. There are no movement dice: your heading and the wind decide how far you sail, and the wind rose turns a set amount each round with a two-round forecast, so you plan your route before committing to it. Buy cargo cheap at one port, sell it dear where it's wanted, hire a crew of sailors and marines, and fight boarding actions with a card-based battery deck instead of a die roll. Pirates hunt loaded ships; islands and delivery contracts decide who wins. 2–6 players, two very different maps.
Iron Rails
Iron Rails is a route-claiming strategy game across five real-geography boards, from a 26-city Western-Europe starter to a full 49-city map of Europe. Collect coloured train cards, spend them to lay track between two cities before a rival claims the same route, and complete secret destination tickets for points at the end. The tension is entirely social: you never know which routes your opponents are quietly racing you for until it's too late to reroute. 2–4 players.
Claimridge
Claimridge is a settlement and resource-trading strategy game across six boards, each built from its own terrain layout — one drops the desert entirely, another splits the land with a water canyon crossable only at two passes, a third adds gold fields that pay a wild resource on anyone's turn. Roll for resources, trade with any player at the table, and build your roads and settlements outward before the best spots are gone. 2–6 players, with dedicated 5–6 player boards so a full table never runs out of room.
Thornwood
Thornwood plays area control differently: instead of racing to a fixed score, the match runs on a calendar of four seasons, each nudging one rule (spring adds musters, summer sharpens attacks, autumn pays double, winter strengthens defence). Every clearing has exactly one owner, shown plainly on the map, and combat is two numbers and one comparison — power plus a public, countable thorn-card draw — so you can always see the odds before you commit. A capture keeps everything the loser had banked, which makes the leader the obvious target rather than a runaway. 2–4 players, three boards.
Crownfall
Crownfall is a world-conquest strategy game across five maps, from a phone-sized original continent to full layouts of Europe, Asia and the Mediterranean. Recruit, assault a neighbouring territory, and fortify what you hold; controlling a whole region pays a recruitment bonus the moment you complete it. Combat resolves as independent hit rolls on both sides rather than a simple compare, so a full assault can genuinely overrun a small garrison in one strike — and a well-entrenched territory earns real defensive pips for the effort. Warrant-card sets escalate the value of every later assault. 2–4 players.
Coralbay
Coralbay is the odd one out on this list on purpose: an engine-building strategy game with zero direct conflict. Feed, breed and scout across three depth bands of a coral reef, settling creatures whose abilities chain left to right — the one you place first in a row activates first, and a filled row sends a bonus activation into the row below. There is no attacking, no elimination, just a private chart of goals and a shared feeding tray that refreshes every turn. If you want the planning depth of a strategy game without anyone able to wreck your position, this is the one. 2–4 players.
