The list might change if more developers bring their titles to the Linux platform
Steam for Linux has already garnered quite a few interesting games, but some of them will stand out due to their quality. We compiled a list of the most interesting titles that are working right now and have the most potential.The list is not put together in any particular order, but it does respect one condition. All the games mentioned here are working and are not in Beta, with one guilty exception.
The Penumbra series is one of the most thrilling experiences a gamer could want. Developed by Frictional Games, it marked the rise of a truly terrifying genre that will scare people to the bone.
The Journey Down: Chapter One is a classic point-and-click adventure developed by the Skygoblin studio. It's fun and benefits from an art style that sets it apart immediately. We reviewed the Linux version of the game and we recommend it to everyone.
Unity of Command: Stalingrad Campaign is a less known strategy game, but it's one the most complex and intensive titles that you can find, at least on the Linux platform.
Amnesia: The Dark Descent is also a horror game and it's developed by the same studio that did Penumbra, Frictional Games. Needless to say that it provides a thrilling and unforgettable experience.
Crusader Kings II is described as a pausable real-time strategy, in the vein of Europa Universalis. In our review, we call it “the only historically accurate back-stabbing simulation in the world”.
FTL: Faster Than Light is described as a “spaceship simulation roguelike-like” by its developers and it's probably the best game that came out of Kickstarter, so far.
X3: Reunion is the ultimate space simulation and probably the only possibility to play a game in the likes of Eve Online, without a subscription.
Bastion is an action role-playing game in which the narrator reacts to the players actions and not the other way around. The art style and the gameplay will make it impossible for players to not fall in love with this title.
Serious Sam 3: BFE is probably the most hardware intensive title in the Steam for Linux library and it also probably features the best graphics. The developers have been patching it constantly and have improved it on a daily basis.
We would also like to include, in a special category, Half-Life and Counter-Strike 1.6 Beta. Even if they technically still in the Beta stages, the games are very stable and quite playable.
