The Amiga version of this game is the best IMHO. :)

definitely doesn't have the same feel as the original but here is a complete flash remake of this game http://www.cinemaware.com/browser/dotc/final.asp

Yeah, that flash remake has been around for a long time now. At least since the remastered versions came out. Sometimes I play it, but the main problem is that unit transfer seems bugged. There doesn't seem to be a way to leave troops in different territories. They all get sent to your capital or your army. So your other lands get left undefended.

I tried to play this game before, but I just did not get it. Maybe someone could give me some pointers on what to do when you start the game, just enough so I can get going and start to enjoy it?

I've heard that Conqueror was based off of this game, so I really wanted to try it. I just beat Conqueror again so I'd like to give this game another go!

Sometimes a couple small tips from people who have played it can go a long way.

Here it is at GOG
