Fantasy Wars is a game with very good tactical turn-based battles. Nothing more nothing less.
The basic idea is this. You command a few heroes and other military units. You fight a lot of enemies and achieve some goal such as conquering a city. Then you move on to a new mission and do the same kind of thing. This is a lot of fun. Why? Because the tactical battles themselves are really good. For example thee are terrain bonuses that differ between military units and make perfect sense, e.g. elven archers may gain defence if hiding in the forest while knights will have a reduced charge attack score. Add to this a large number of different kinds of units to command, many of which are upgradable, several different heroes with unique skills and different skills to choose from for each type of unit when it levels up. Together it adds up to a challenging and fun to play turn based strategy game.
The story is the weakest element of the game. I cannot even remember what it was about and i just finished the game. But it doesn't really matter. This is not a game you play for the story anyway.
The interface is well designed and easy to understand and to use. There are three different campaigns, one of which is unlocked after you have beaten the other two (in either order). You can choose one of three difficulty level separately for each mission and there are also three different victory types depending on how quickly you finish the mission. This adds some replay value to what is already a long game.
Graphics are fairly good but nothing exceptional. Voice acting is okay, not bad but could have been better, although as with the story it doesn't make a big difference.
All in all I would highly recommend this to fans of turn-based strategy, but not really to anyone else. It offers great tactial turn-based battles if you like that. If you don't there is probably not really anything in it for you.
