0 A.D.


0 A.D. is a free (as in freedom) historical real-time strategy game which tries to portray some of the major civilizations over the millennium of 500 B.C. to 500 A.D. and thus has a great variety of civilizations you can choose from, such as Athenians, Macedonians, Persians, Romans, Spartans and many more. It is comparable to Age Of Empires and features epic battles with very large armies, either against an AI or in multiplayer matches. In fact it actually started as a mod concept for Age Of Empires II: The Age of Kings, but evolved to a standalone game with it's own engine, Pyrogenesis. It is still considered alpha and is not feature-complete, but already has a small and active gaming community. You can hang out in the gaming lobby and challenge other players.

Dune Legacy


Dune Legacy is a free remake of the classic Dune II with reworked graphics, improved gameplay, AI and controls while still maintaining the original game flair.

FreeCiv


FreeCiv is a free 2D turn-based strategy game inspired by the Sid Meier's Civilization series. The gameplay is like that of the Civilization series, in which the goal is to lead a civilization from 4000 B.C. until however the game ends. The player can discover technologies, conduct diplomacy and/or wage war, build cities and many other things. The game may end when a set year is reached, when one civilization has eradicated all the others, or when one civilization has accomplished the goal of space colonization. These are different win conditions that may be enabled or disabled. This type of customisability of the gameplay rules is characteristic of FreeCiv which has a list of settings that are probably overwhelming to new players but very rewarding once you get the hang of the game. It is a very deep game with very deep game play. FreeCiv has networked multiplayer (LAN or Internet). It may be played in several different clients. In Portage, we have the GTK2 and the SDL clients (use gtk and/or sdl USE-flags), of which the GTK2 one is arguably the most pleasant. The game may also be played online in your browser using the HTML5 version. View a YouTube demo here.

Hedgewars


Hedgewars is a turn-based strategy, artillery, action and comedy game, featuring the antics of pink hedgehogs with attitude as they battle from the depths of hell to the depths of space. Each player controls a team of several hedgehogs: during the course of the game, players take turns with one of their hedgehogs. They then use whatever tools and weapons are available to attack and kill the opponents' hedgehogs, thereby winning the game. A large variety of tools and weapons are available for players during the game. Hedgewars features the standard artillery-genre classics (such as Grenade, Cluster Bomb, Bazooka, Shotgun), but also boasts a host of other weapons quite unique to it alone.
