I like the idea of a “rally” button. Someone else mentioned it earlier. But that would surely let you call people back who had gotten lost, call in new people who spawned so far away they can’t find your camp, and solve the starve to death problem, because you could rally near food.
Also the button could be on the same panel as the “call to arms” button.
In terms of gameplay, I believe Radiant has taken the approach of releasing each alpha as a “mini” game (at least, this alpha, 4, expresses that best). And by “mini”, I mean a small amount of gameplay but actually a game. They have tried to balance things for the release so there is something playable.
I think this is a wise choice. Instead of just adding tech to the game and releasing new versions with new (but unusable tech) they have made each release a “game” of sorts. As I said, I think from a game company and development shop choice this is wise, and will bear much fruit in the long run.
Stonehearth IS the first mod. So each time they increase the tech they have to rewrite the mod to use the new tech. Soon that total rewrite process should fade and the core game will be able to go from tech release to tech release. But the practice of rewriting the game/mod each time by the Radiant team is incredible, invaluable experience that should make a better game in the long run.
