This game combines elements of RTS, RPG, First & Third person hack and slash and management all into one game. Unfortunately it is a classic case of jack of all trades but master of none. This doesn't mean to say though that this is not a fantastic game. On the surface it has it all, but once you put the hours in and scratch a little under the surface it does feel a little shallow.
I think the fun in the long term is the character builds and user defined story - Do you want to be a noble, holding and managing kingdoms that spread far and wide? Do you want to be a hired mercenary and embark on conquests for the benefit of your liege? Do you want to run businesses and build an empire of wealth and legacy to pass on to your heirs? You can do it all.
