This one's a niche little Game Boy gem if you're into learning English—specifically, English idioms and phrases. It's part of the Goukaku Boy series, which basically means it's designed to help Japanese students prep for exams, but don't let that scare you off. You get quizzed on 1000 common English expressions, picking the right translations from multiple-choice answers.

At first, it feels like a straightforward flashcard game, but the pacing keeps it from getting dull. The questions ramp up in difficulty, and there's something weirdly satisfying about nailing a tricky one. The pixelated interface is pure early '90s charm, too—no frills, just functional. If you're brushing up on English (or just love retro edutainment), it's a fun little time capsule. Definitely not for everyone, but it’s got its own weird appeal.
