Sangokushi - Game Boy Ban 2 (Koei, 1999)
A Romance of the Three Kingdoms game that looks like it would be a strategy game, except that everything seems to be controlled by the computer. I was able to pick a starting date and then watch 15 CPU players take their turns before the month counter incremented to February. Not sure why anyone would want to do that.
Sanrio Timenet: Kako Hen (TOSE/Imagineer, 1998)
A Pokemon knockoff with a "Past Version" and "Future Version", of which this is the former. You have to get through a whole lot of long winded exposition to reach your first battle, and as you can see, that's an extremely low-budget affair. The music is terrible and the overworld I saw was barren, which all points towards this being a rushed attempt to cash in on the craze.
Sanrio Timenet: Mirai Hen (TOSE/Imagineer, 1998)
Exactly the same game as the above except that your starting three choices of Pokemon-equivalent are different.
Santa Claus Junior (Neon Studios/JoWooD Productions, 2001)
Hyper generic platformer that still manages to have bad music even though they could've just recycled a bunch of public domain Christmas music.
Scooby Doo! Classic Creep Capers (Software Creations/THQ, 2001)
A Scooby Doo adventure game I'm pretty sure I played as a kid, although it wasn't my cartridge. I remember it being decent, and the introductory sequence was well made, so it's off to the list with this one.
Scrabble (Runecraft/Ubisoft, 2001)
If I was going to make a Scrabble video game, I'd at least make sure to not color the board like a mold growth. But I'm not going to make a Scrabble video game, and I'm also not going to play someone else's Scrabble video game. I don't like Scrabble, you see. It's course, and rough, and, wait, that's something else.
SD Hiryuu no Ken EX (Culture Brain, 1999)
A fighting game with a huge cast of characters, surprisingly good backgrounds, and great music. I am no good at fighting games and may not be able to get very far in it, but it's definitely one for the list.
Seihai Densetsu (Gaps, 2000)
A mahjong RPG. It's neat that someone wanted to make a story mode for mahjong, and they did a decent job with the art and music. But, as you may have figured out from all the other mahjong games, I don't know how to play mahjong.
Seme COM Dungeon: Drururuaga (Kuusou Kagaku/Namco, 2000)
A roguelike where you can play cards to determine what monsters appear in each room and to access special abilities. Unusually for a GBC game, it has a very involved textual tutorial before you actually get to play. Not my genre, but it seems potentially cool if you're into these games.
Senkai Ibonroku Juntei Taisen: TV Animation Senkaiden Houshin Engi Yori (Banpresto, 2000)
All the money seems to have gone towards printing that ridiculously long name, because this is an impressively graphically barebones SRPG. There've been others that do this lame colored square approach to units, but most of them at least didn't make 60% of the first map just a black void.
Sesame Street: Elmo's 123s (Bonsai Entertainment/NewKidCo, 1999)
A game that is presumably meant to teach kids about counting. You need to point the search light to the right number of stars, and every time you get it right you have to sit through the same 20 second animation before the next test. There are other minigames, which are probably just as bad.
Sesame Street: Elmo's ABCs (Bonsai Entertainment/NewKidCo, 1999)
Ever the Michael Jackson imitator, Elmo made a second game for the other half of the song. This one is somehow even slower. You would not believe how long it took for the 'B' to finally rotate around, and even after that there were more animations to sit through before the next question.
Sesame Street: The Adventures of Elmo in Grouchland (Bonsai Entertainment/NewKidCo, 1999)
Elmo lost his blanket and needs to chase it down. It's nice enough to wait for you if you stop running, but then it dives into a garbage can and you have to play a horrible falling game. If you hit too many things, you have to start all over even though it moves at the pace of molasses. Elmo, truly the Sisyphus of our modern age.
Sesame Street Sports (Bonsai Entertainment/NewKidCo, 2001)
Despite being called "sports", it made me do this dumb ball bouncing minigame two times in a row. It's possible that each character only has one minigame, so I was guaranteed this by picking Cookie Monster, but that's not how a sports game should work. Cookie Monster demands to play baseball!
