Perhaps the most anticipated title under Nexon Korea, it has been known for some time that players are able to build their own landscapes in Peria Chronicles. Just to mention, developer Thingsoft is now part of Nexon Korea after a studio purchase last year, if I remember correctly.
From the trailer, which introduced several antagonists for the first time, it can be seen that players will be able to customize almost everything, from housing doors to laying traps in dungeons. The mini-game feature only consists of a Tetris-like mode, but I am sure more will be added in the future.
