For me, it's Gadget Racers (US) (!) on the GBA and King's Bounty on the Genesis. I've completed both games hundreds of times by now. King's Bounty is great because the scepter is in a different location each time you play. Sadly, the second Kings Bounty is nothing like the first one.
Tears of The Kingdom is turning into a comfort game as well. Sometimes, I just build things or look for fucking Koroks and their over packed backpack. FFS guys, thats why you cant move. I'd travel by vehicle, horse (this is a vehicle?), or foot looking for those little bitches. I fight all along the way and my inventory is crazy, so I should probably upgrade my armor soon. I really like the fairies.
