Whilst any attempt to combine genres is normally to be applauded, in the case of Crusader it is to be destroyed.
Because the grow-crops, buy-troops bit is just pointlessly undemanding, and the 3D jousting "moments" tread the piano wire separating gameplay tragedy from graphical farce.
Do you remember that old Robin Hood Amiga/ST game? It has a map just like that. But that doesn't mean anything!
