A quick question as title suggests - the reason I asked is, if I understand properly, I think Research System can fulfill what Ability Tree or Crafting System does.
Ability trees can be completely replaced by the research system (and this will probably happen in ORK 3).
Crafting could also be done via research system, but crafting recipes still have more useful features for crafting. Crafting menus can show ingredients of a recipe or you can just thrown together stuff from your inventory to craft stuff (based on matching recipes). Also crafting recipes can use game events for additional features and have a critical outcome (e.g. create 2 potions instead of 1).
Please consider rating/reviewing my products on the Asset Store (hopefully positively), as that helps tremendously with getting found. If you're enjoying my products, updates and support, please consider supporting me on patreon.com!
