Oh, and I also imposed one simple rule: I'm only counting games that were commercially released in the heyday of the system (1985-1995). So no homebrews or reproductions, no unreleased games, and none of those penis-laden racist ROM hacks every twelve year old with a copy of Microsoft Paint churned out back in the late 90s.
100. Hydlide (T&E Soft, 1989)
Hydlide honestly wasn't a bad game for its time; it was one of the first action-RPGs ever released on Japanese computers, and had quite a bit of longevity and content for a game that ultimately took up less than 40 kilobytes of space. The big problem was that its time was in 1984 and it ultimately didn't get published in North America until 1989 - five years after its original debut and two years after the vastly superior Legend of Zelda. So everyone who saw a screenshot or two and expected another Zelda-esque adventure ended up being extremely disappointed, which was understandable, if a bit unfair. Also not helping Hydlide's case was a heavy emphasis on grinding and touch-based combat make it a chore to play, essentially boiling the entire process down into long bouts of enemy bopping interlaced with a lot of savescumming. So while it was a pioneer for the genre, Hydlide's only value nowadays is as a curious footnote for RPG fans who want to see where the (much better) Ys series drew its inspiration from.
99. Friday the 13th (Atlus, 1989)
98. Renegade (Technos, 1987)
97. Advanced Dungeons and Dragons: Hillsfar (Marionette, 1993)
96. Wall Street Kid (Sofel, 1990)
One of those "why does this even exist" games, Wall Street Kid, as its name suggests, is about investing in the stock market to earn a big enough profit in order to not be disowned by your rich family. Exciting, right? Well, even the developers seemingly thought that weak premise wasn't enough to carry a game, as they tried to work in a dating sim element as well - you have to work out to maintain your health and spoil your girlfriend by buying her things and going on trips with her, or your character will fall into depression and end the game. So if you ever wanted to play a simulation that highlights the life of being a negative stereotype of a rich person - shallow, greedy and obsessed with lording their wealth over others - I guess this is the game for you. The rest of us would probably be better served by investing in a more entertaining game. Or in the actual stock market; your choice.
