Soreike! Anpanman: 5tsu no Tou no Ousama (Graphic Research/Tamsoft, 2000)
A very basic puzzle/adventure game with terrible character design and inconsistent music. The track that was playing when I took this screenshot was actually good, but it's too short and recycled for each new puzzle level.
Soreike! Anpanman: Fushigi na Nikoniko Album (Graphic Research/Tamsoft, 1999)
The character design is just as bad in this game, but at least you can run so fast that it feels like some dev accidentally left a super speed mode on. You're collecting pictures of people by walking next to them and occasionally being interrupted by the bad guy to fight random battles that feel like WarioWare-reject minigames.
Soul Getter: Houkago Bouken RPG (Micro Cabin, 2000)
I love the battle graphics for this game, and the writing seemed decent from what I played. Unfortunately, the music is absolutely abysmal and heavily features what sounds like an out of tune recorder, so I won't be coming back. I can't take listening to that for more than a few minutes.
Space Invaders (Crawfish Interactive/Activision, 1999)
Another GBC update of an ancient arcade game. It's a little impressive that they got it working with four rows of enemies on such a small screen, but at the end of the day it's still just Space Invaders. Not something I really ever need to play more of.
Space Marauder (KID, 1999)
It's weird to call a game where your character can freely rotate shot direction a shmup, but I don't know a better genre for it considering it's also an auto-scroller going left, you're expected to shoot all the time, and enemies come from the left in formations. It's kind of fun with the sound off, but unfortunately they decided to have each shot make a high pitched noise, which of course means that's going off constantly because this is a shmup. No thanks.
Space-Net: Cosmo Blue and Cosmo Red (Imagineer, 2001)
A JRPG where you're exploring a system of seven planets and can drive around on the surface in a tank. I also saw, but didn't explore, a lot of options on the ship menu for things that looked like crew management and scientific research. Since this is basically JRPG Mass Effect, you better believe it's going on the list. The only difference I saw between the two versions was the design of your tank and the color of the exploration items you get from HQ.
Spacestation Silicon Valley (Tarantula Studios/Take-Two Interactive, 1999)
I do not understand this game. It opens with a sketch about an old man and a robot fighting over the music in a space ship, so they're distracted and crash into a space station. They land on top of a dog who has just proposed to a sheep, and then the eject button goes off and conveniently sends the robot into space, which causes it to break into pieces for some reason. Then you play as the dog, who is miraculously okay and needs to collect energy and sleep. On top of all that, the music sucks.
Spawn (Konami, 1999)
It's been a long time since the last superhero brawler, but here's another one. The controls and graphics are quite bad, but at least the music is decent. My favorite part is that you fall down if you walk into a bad guy from behind.
Speedy Gonzales: Aztec Adventure (Sunsoft, 1999)
I put this on my list of crappiest games I've ever finished because the only way it knows to increase difficulty is to hit you with cheap tricks. You wouldn't know that from the first few screens, though, which suddenly has me a little worried for a few of the games I've put on the list. How many are going to be like this and only reveal how bad they are in later levels?
Spider-Man (Vicarious Visions/Activision, 2000)
This is supposed to be a brawler, but they somehow didn't stop to think about the implications of letting you swing off the skybox indefinitely with nothing but a few hapless birds to try and stop you. As long as you have something tall to start your swinging from, you can just skip the entire level.
