hard choice.... war of 1917 only because! age of war there could only be one person at a time attacking eachother, turrents also had way too much range = too easy to win, just buy 3 blue turrents.
I think war 1917 is definately the winner, although there a lot of things i dislike about both of them....and im not goin to re post the comments i made on the games themselves. I would like it if there was more levels i the campaigns so i could actually unlock all the commands without playig each level until the enemy surrenders. All in all war 1917 simply offers more variety. You can choose trench warfare or open battle. altho i get really anoyed when enemy tanks refuse to be destroyed by my support fire :P
I like age of war. its much more straitforward, I love advancing through ages, and really love watching my enemy make a ton of troops including about 3 tank-style tropps then i use a special that destroys them all completely.
