Battle for Wesnoth is a full turn based strategy game, available on a number of platforms. Notably on Linux because we dont get many games here!
You can get it in the repositories be installing "wesnoth".
Graphics:
The graphics are well drawn and it has the sense of a game that you would pay for. There are loads of different character types and each one has a different image, theyre not just edited with different colours.
8/10
Wesnoth has great level designs, despite being limited to a hexagonal grid
Gameplay:
As a turn-based strategy, Wesnoth has lots of different factors in gameplay. Units level up, and have various statistics, multiple weapons (which also have lots of stats). Playing in the night changes your units abilities, or playing on different terrain. At first it can seem a lot to get your head around but it really makes playing more fun when you have to review all the stats before you make a move. Its also got a battle calculator so you can predict the possible outcomes of each battle before you attack.
9/10
Level, HP, XP, MP, Defence, Allegiance and weapon stats all to consider
Game time:
Wesnoth has a extensive single player campaigns and and multi-player over the internet, so it doesnt get old. Single player will last you a while if you play a few hours a day and once thats done you can have countless battles over the internet (which is even more exciting, in my opinion).
9/10
There are 15 campaigns, most with over 10 scenarios
Overall:
In conclusion, Wesnoth is an amazing game which, being free, is something you really should try because on Linux its one of the best games available.
