Summary: If you dev a war game with maps and scenarios, include a custom scenario editor that is EASY to CODE but VERY SATISFYING. Here is a revolutionary idea.
Background: I'm retired and I enjoy a now-seasoned game called Blitzkrieg 2; I play in Win 7 and game works great. But the Editor freezes in Win7. The editor is complex and likely never got tuned forward from WinXP. That editor was obviously a HUGE DEV PROJECT and custom games can be found (e.g.) that are vast and remarkable, so it was a great editor. But the editor not getting updated to Win7 is understandable. Blitzkrieg 2 is available for $9 Amazon Prime here.
Idea: Instead of coding, documenting, maintaining, and supporting a complex map/scenario editor, just provide say ~200 randomly generated maps, independent of the leveling up, for custom games. Tell the users, "Here is a very simple no-learning-curve editor where you choose one of these maps and set any units, locations, and objectives that you desire. IN OTHER WORDS THE REVOLUTIONARY MAP EDITOR CONCEPT IS VERY SIMPLE AND LIMITED; it just allows point and click to set unit and objective locations and some simple screens to specify reinforcements, number of turns, etc."
Users Will Love It: They can skip the usual complex editor learning curve and just learn a couple really simple dialogs. But they still have endless flexibility to generate custom contests.
Business People and Devs will Love It: They do much less work on the editor phase, both in dev and support (also in documentation), but they still get positive feedback and strong sales.
