I tried out the campaign for Wargame : Airland Battle by Eugen. It is a brilliant game and the campaign was designed in the form of a 'dynamic' campaign similar to that of the famed Total War series. It is a refreshing improvement from the linear and uninspiring campaign that I played in Wargame : European Escalation.
In this dynamic campaign, your actions on the battle map will directly influence you on the campaign map. For instance, if the AI wins, then you will find that you have lost some territory on the campaign map. Correspondingly if you win, you are rewarded with the necessary morale points to win the scenario. You can watch me play the first scenario in this video.
In the following video, you will see that my victory on the campaign map wins me the necessary territory to achieve victory for the scenario. This campaign mode seriously makes me want to up my game and take each battle seriously. Because I know that there is an incentive to win. In addition, there is a time limit for the campaign and as a result you do not have infinite time to win and therefore it to your benefit to win all or most of the battles.
This is undoubtedly a great game and the campaign is a nice change. It provides a significant challenge and I am sure that you will spend time trying out the scenario repeatedly to carve out a win.
