I would only recommend short games. Ive been gaming my whole life and basically quit recently, because I was playing grindy games that were so exhausting mentally.
Even great games like Terraria, Minecraft and dont starve leave me exhausted. Such huge time sinks. Ive moved onto hobbies that are much more satisfying.
Knife sharpening. Not hard to learn how to do it decently, and hard to find someone who can do it decently. The equipment is not too expensive either. 40$ for a good coarse stone (you will need one!!!) And 40$ for a decent combo stone of medium and fine. You probably want a good flattening stone too.
DONT use amazon, all of the stones there are scams. A good coarse stone is a Naniwa lobster 220. A good combo stone is the KING KDS 1000/6000.
