Dino Breeder is one of those weird little Game Boy gems that somehow makes raising pixel dinosaurs way more addictive than it should be. You start with a couple of basic dinos—I always went for the stegosaurus first—and then it’s all about feeding them, keeping them happy, and hoping they don’t randomly decide to hate each other when you try breeding them. The sprites are tiny but full of personality, especially when they do their little happy animations after a meal.

There’s something oddly satisfying about unlocking a new species after messing around with different combos. I remember wasting half an hour trying to get a triceratops and a raptor to cooperate, only to end up with this derpy hybrid that looked like it couldn’t decide whether to be cute or terrifying. The habitats are simple but fun to customize, and watching your dinos grow from hatchlings into full-grown beasts never gets old. It’s definitely janky in that classic Game Boy way, but that’s part of the charm.

If you ever played those old-school virtual pet games but wished they had more teeth (literally), this one’s worth digging up.
