What a rich and deep game. I'm not like a lot of folks here who've played every version. (I think I might have played II or III.) Still, I'm really impressed with what they did, and the sheer addictive nature of the thing. For some reason, the early game feels a lot more compelling than the late game. The acquisition of gun-powder and canons really feels climatic. Maybe that's why I haven't finished a full game yet.
