Gekitou Power Modeller is one of those weird, niche Game Boy titles that makes you go, "Wait, they made a game about this?" It's a Japanese-exclusive where you build and customize miniature plastic models—think Gundam kits but with a retro gaming twist. You start by picking a base model, then go hands-on with tiny parts, painting, and even test battles to see how your creation holds up.

The controls are clunky by today's standards (it is a Game Boy game), but there's something oddly satisfying about tweaking your mech's balance or swapping out armor pieces. Half the fun is seeing how badly your first attempt falls apart in battle before you figure out the right part combos. If you're into model kits or just love obscure retro games, this one's a neat little time capsule.
