loved the game, a tribute indeed to old school rts, tough days for rts fans right now :C
its very hard for me to find anything wrong with this game, maybe more missions? more evils kings , maybe a dragon? (yeah thats right we do not have enough games with dragons)or maybe an evil wizard who wants to take over with an army of skeletons and everytime u get a casualty on your side it comes back as an hostile skeleton? and what not, an sneaky group of assassins that have the habit of popping almost anywhere and start fires? maybe civil unrest? like part of your army revolts or something, dondt know just brainstorming here, just wished there was more stuff to do or more situations to deal with.
hope u r thinking about a second part :D out of that , awesome work!!!
