Best strategy game in my opinion.
There's like nothing wrong with this game - no bugs, no problems, everything's fine. My first strategy game ever :)
It has a lot of levels (50 + 30) that are not boring, repetitive and grow from easy to super hard. I never finished the last levels in the first campaign with 50 levels. The enemies are great, funny, ... "talkative", selfish.... .... But a little stupid sometimes. They do the same mistakes each and every time XD.
The music is obviously perfect for the game. i enjoyed it so much! As well as the voices in the game. You can build your castle in your own way, but also taking care of the enemy's personality, so you should know how to build walls, towers, water pots, etc.
It was a bit annoying that you couldn't make more than 500 troops for example. I am the one who likes to make a lot of troops, just to be sure. 'Abbot' for example can do even over 1k troops, without having any problems.
In conclusion Stronghold Crusader is a perfect game.
