LilithDawson, you probably did not understand well. There are 2 games in developement:
Life Is Feudal:MMO - "typical" MMO, server farm hosted by game provider, thousands players on big map you already posted.
Life Is Feudal:Your Own - 64 players, you can have own server, only that island, we all already know (by buying this game you get also one character slot for upcomming MMO version)
Both games will use similar mechanics. Anyway, they are both separated games
Scroll down to bottom of page you will see and understand
