Is currently the highest rated game on BGG (https://boardgamegeek.com/boardgame/174430/gloomhaven). At $138 its definitely a bargain imo.
From my research, it's suitable for people/groups that are into card management/dungeon crawlers with RPG elements and so probably not for everyone. Can be played solo or up to 4 players.
Potentially a duplicate of this https://www.ozbargain.com.au/node/573806, however I thought it warrants its own post.
Camelcamelcamel shows that last time it was this price was about 2 years ago: https://au.camelcamelcamel.com/product/B01LZXVN4P
I believe it's the last day of the 25% off, so get in while you can :)
