boardgames

Radlands final turns can be so tight, I suspect variant rule is impossible, and alternative rules would be very different (and interesting).

Full alternative rules needs a lot of work as the components are already specified and you have to find interesting mechanism with them. While in board game design, components are shaped to match the mechanism. Very few games had such rules : Traditional game cards and Chess are the firsts who comes in mind, but I suspect War of the Ring also had such alternative rules.
