Heck yeah! I was very late to the party with getting a Game Boy. I was a Sega kid and a Game Gear loyalist. I had a friend with one and definitely could appreciate Wario Land and Kirby's Dream Land, but for the most part I felt like the Game Gear was the better handheld in the 90s. When I was in high school (2000-2004) I was extremely into DOS games and in 2001 I saw there was a Commander Keen GBC game and I *had* to have it - THE FIRST COMMANDER KEEN GAME IN ALMOST A DECADE! So I got a GBC and shortly after Commander Keen. The GBC was my first piece of non-Sega gaming hardware that I bought new!
Well, the GBC Keen turned out to be a steaming pile, but at least I had something that could play Game Boy games! One of my first games I got as a gift: The Simpsons - Night of the Living Treehouse of Horror. I never beat it and seem to have lost the cart, but do have some fond memories of it. Early on I set out to get some Capcom games and got Metal Walker and Mega Man Xtreme. I thought Metal Walker was cool (it was very Pokemon inspired but I liked that it was based on robots and their data rather than Pokemon), but way too grindy and I never beat it. I had rented Mega Man games as a kid and fooled around with Mega Man X on an emulator, but Xtreme was my first actual Mega Man game. It's nothing too fancy, but it's a pretty decent 8-bit conversion of Mega Man X. Let me tell you: I'm kicking myself for never picking up Resident Evil Gaiden or Shantae. They just didn't seem like priority games. I did get some JRPGs that I had never heard of called Dragon Warrior I&II - two old school RPGs on one cart sounded like a deal! I also got Dragon Warrior III but wouldn't play it for some years later since I wanted to go through the series in order and DWII is a slog.
The GBC was pretty much dead at that point with the GBA having taken over so I never got too many more games. I was more concerned about getting things for other systems. Some time after graduating college, I started picking up the occasional Game Boy game. I got into chiptunes and felt the need to mod a DMG Game Boy so I ended up with two of those: one's modded and the other original. It was around this time that I finally got around to playing Dragon Warrior III - WOW, what a game! It instantly became my favorite 8-bit JRPG, easily overtaking the original Phantasy Star. It's probably still my favorite game for Game Boy hardware and is the title that turned me into a hardcore Dragon Quest fan.
But I never felt like I was exploring the Game Boy library all that deeply until the past few years. Listening to the Retronauts podcast exposed me to a bunch of games I wasn't familiar with, especially by watching the host
Jeremy Parish's Game Boy Works series. It got me curious to explore monochrome Game Boy more - only being exposed to games other kids had led me to have massive blindspots about the strength of the system. While when it came to converting popular 16-bit games to handheld, the Game Gear was better. The Game Boy excelled at being the home for quirky puzzle games and slower paced fare. The best GB games are the kinds of games you want to play for 15 minutes at a time but then lose track of time and end up playing for an hour. Tetris is really the best example.
Now I have a pretty sizeable collection of monochrome Game Boy games and an Analogue Pocket to play them on. I love Game Boy now more than ever! I could keep rambling on, but it's just a very cool little system with a very cool, very expansive library! While everyone knows the big first-party games, the Game Boy library feels like a vast uncharted jungle. You never know when you pick up a cheapo cart of a game you've never heard of that you might find a hidden gem! I think it's one of the very few systems where that's true and considering it's one of the most popular gaming platforms of all time, that's pretty astounding!
