@cyc:
you can. the far out cities will take lets say 20 turns to found.
this means you already earned 100 gold by not participating in the game. if we charge 1 gold per tile, you could move out 100 tiles (well, i would prefer more like 0.1 or 0.5 gold per tile, rounded up to the next full gold).
with 0.1 you could move out up to 1000 tiles, which is almost around the world. we wont be able to build such far-out cities within 20 turns though.
you see, even with full ruleset, there will be the possibility for the non-participating citizens to move around the country. together with public housing in all cities and a free-startoff city (you can choose the city you like without cost when you register the first time).
if we use rules for it, they should apply to all. otherwise they would be unfair to the ones participating.
