The gameplay wasn't fun. What I consider a good B&D gameplay includes tough enemies and 1h+ struggle to win. I won this one without creating any extra units or researching any tech. My army of pikeman, crossbows and attack buffed Teutonic Knights swept across the map, but I had to use I R winner to win as one of the (non-custom) AI didn't want to surrender. Reason? 25 champions in a corner. behind forest. Surrounded by water. Behind more forest. First step towards a better gameplay are custom AI that would fit the setting you made better. AI&RM forum offers tips and tools and I'm sure they'll help you. 1 for now.
The lack of custom AI and diplomacy triggers ruined it, as well as the boosted teutknights. I simply moved my units into enemy bases, changed diplomacy and killed everything. Only the speed of teutknights made it 18min long. Again custom AI is the key or the foundation of such scenario to be good. Too primitive to be given more than 1.
I haven't found anything particularly innovative, neither I give score to the story here, as nothing is present to depict it. There are also dozens of similar files around the Blacksmith that use simple ingame AI and poor story. Sadly 1.
On the level of RM. No special eye-candy, no particularly eye pleasing parts, not a single tile of elevation on the map and poor terrain mixing. Both elevation and terrain mixing are the key to nice looking map design. Visit SD&D more, play scenarios that received high marks on map design and try to copy it first, before developing a style that you find nice. 2
Nothing present. If you want people to understand the reasons behind the war they are playing in the scenario you have to tell them that. Also write hints to help the player if needed. Write the objectives and instructions. 1
Additional Comments: Play some well received B&D scenarios and try to learn from them. I suggest Kings of Destruction by Bassi.
