I've played through age of empires 2 many times throughout the years, so naturally when I saw a DLC for it that includes a brand new campaign I was pretty excited and got it immediately. One thing that I noticed, however, that is fairly gamebreaking (for me at least) is the user interface in regards to grouped unit movements. In AoE 2 original, the group movement feature (assuming it has something to do with how the code was written) was much better. In The Forgetten DLC, you can have lets say a group of 10 troops, 2 of which are very close to an enemy that you want to attack and 8 of which are a few seconds away. When you order that group of 10 to attack, the 2 that were close to the enemy will run all the way back to the other 8 to get back into formation, and then the group of 10 will advance together. This makes it really difficult to micromanage battles, and just makes movement in general feel very unsmooth and shaky. Just something to consider when purchasing the DLC. The campaign itself is decent for now, haven't played too much of it but it seems alright.
