This is hands down, one of THE best games i've ever played for the PC. The graphics are fantastic, and it stays along the lines of the previous, Stronghold game versions.
The big difference between this one and the others, is the "mythalogical" factor. You are able to have creatures who can cast spells, Dragons, Giants, etc. There are three ways to play as either Arthur, the Ice King, or the Evil King. Depending on who you choose, you get different creatures you are able to use.
Each mission is different, with a objective for you to complete to continue. Your generals have spells they can cast, and can use them in "hairy" situations.
If you have a slower video card, then this game isn't for you as there is tons of action, and the gameplay can lag. I currently run a NVIDIA 8800 and can run this on full speed, without any lag.
This is a must have for the fantasy gamer, or if your looking for a strategy based game!
