39. Wally Bear and the NO! Gang (American Game Cartridges, 1992)
ineffective "Just Say No" campaign from the 80s and 90s, and it makes about as compelling as a gaming experience as you'd think. Go through generic level full of enemies (whom you defeat with awkwardly-thrown frisbees), traverse platforms with clumsy physics (unsurprising since you're on a skateboard), get a short speech about the evils of drugs and booze, eventually finish the game. Contending with generic and ugly visuals and ear-piercingly shrill music certainly doesn't help its case either.
38. Baby Boomer (Color Dreams, 1989)
37. Ikari Warriors II: Victory Road (SNK, 1988)
36. Darkman (Painting By Numbers, 1991)
35. Captain Planet and the Planeteers (Chris Gray Enterprises, 1992)
34. Hydlide (T&E Soft, 1989)
Hydlide honestly wasn't a terrible 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. 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 and Zelda franchises drew inspiration from.
33. Muppet Adventure: Chaos at the Carnival (Mind's Eye, 1990)
32. Ghostbusters (Micronics, 1986)
featured in the (much better) 2009 Ghostbusters game as a joke.
31. Pesterminator: The Western Exterminator (Color Dreams, 1990)
pest control company (which has also seen use in many other venues). But hey, even corporate icons have had a surprisingly decent game to their name here and there, so maybe Pesterminator won't be all that bad, you think as your mind races to games like Yo! Noid and Cool Spot for the 16-bit systems. Then you remember that Color Dreams is at the helm, which means that the game is just a boring exercise in walking from room to room, smashing each and every bug you come across with your character's mallet, and them moving on to the next stage where you do it all over again. Complete the package with excessively loud sound effects and a garish color palette that makes the whole experience an extended exercise in torment, and Pesterminator is a lousy game based on a lousy concept.
