Monster Taming is hitting a monster to a certain health level and extracting a core from that creature. With 3 cores and some resources, you summon one. Once you have a solid stable of creatures, you can start breeding them. Your monster party size is 6 - turn based, JRPG style combat.
Crafting also comes in artifacts, portal stones, things to make your monsters stats jump, spells....the list goes on.
All of the dungeons are procedurally generated, there are 15 tile sets each with their own god who have favor to keep track of. Befriending them gets you direct teleports to their tileset, a creature and an artifact (at least that’s true of #2).
The list of stuff to do got bigger too. So overall, it’s a solid game for the price.
