Let's Play Every Game Boy Color Game, Part 42
Metal Gear Solid (TOSE/Konami, 2000)
I'm not sure how I didn't know about this game already, considering it's by some measures the single highest rated GBC game ever released, but here we are. Rather than being a port of the PSX MGS, it's an alternate timeline plot set around the same time in a completely different location. I didn't really see gameplay because the opening cutscenes are, being Metal Gear, eternal, but the writing is very good. To the list!
Metal Walker (TOSE/Capcom, 2000)
The original Japanese version already showed up on this list as Bakusou Senki Metal Walker GB, but that was before I'd decided to only cover the English or original version of each game. It still has a bizarre battle system that involves basically playing pool with your monster to try and smash the other one into bits, but the highly questionable English grammar is obviously new to the translation.
Metamode (Koei, 2000)
A Zelda-like game that seems to have stolen its tree sprite. I think there's a mechanic where you can change into a monster form (the titular "metamode") and it seems like it has a pretty big cast of characters. I didn't get to see much because MGS took a lot of time and this was also long winded, so I had to mash to make sure I can get to everything today. But it seems interesting so far, so to the list it goes.
Mia Hamm Soccer Shootout (Aqua Pacific/SouthPeak Interactive, 2000)
Although notable as one of the only women's soccer games I've ever seen, it's not really very good. Slide tackles work from about 30 feet away and make it impossible to run with the ball basically at all, and it's hard to have much idea of what's going on when the camera is so zoomed in. On top of that, there's no stadium noise or music at all, so you play in complete silence.
Mickey's Racing Adventure (Rare/Nintendo, 1999)
Despite the name, what I saw of this was a long unskippable cutscene, an overworld section where Mickey is like 10 feet tall, and then a slide puzzle. It has good music, but this is approximately the least appealing IP in the world to me.
Mickey's Speedway USA (Rare/Nintendo, 2001)
It's Mario Kart, but bad. You can hardly see any of the track, the graphics are terrible, and it's not even clear what some of the powerups do.
Micro Machines 1 and 2: Twin Turbo (Virtucraft/THQ, 2000)
Ports of the first two Micro Machines games. They're fun, if simple, arcade racers as always. I can't imagine this was ever the best way to play them, but it'd be fun on a trip or something.
Micro Machines V3 (Novalicious/THQ, 2000)
MMV3 came out about 10 months later and doesn't seem to add a lot beyond having more content. The graphics are pretty comparable and I didn't see many new modes, but I wasn't looking that hard. I had a PC version of this that was very different, so I have to imagine the GBC game was kind of throwaway.
Micro Maniacs (Hyperion Studios/THQ, 2001)
It's basically another kart racing game, except this time you're actually a bunch of mouse-sized bipedal creatures running around a track. That's maybe not the worst idea for a game, but most of it feels unfinished. It doesn't bother to explain much of anything, the menus are often almost solid color, and there's not much music until you get into a race.
Microsoft: The 6-in-1 Puzzle Collection Entertainment Pack (Conspiracy Entertainment/Classified Games, 2000)
A port of a collection of 6 puzzle games that Microsoft originally published on PC. You'd probably expect 6 public domain card games like you usually get from MS tie-ins, but apparently they got the creator of Tetris to design a few of them, and they're actually fairly unique. The one above tasks you with picking up all the gems, but when you touch a square of a different color than the one you're on, you warp to the next square that matches your color in that line. Seems neat, but not a genre I really enjoy.
