Let's talk about those depressing instances when a PCE/Turbo game let you down. Here are some games that I was disappointed with:
Magical Chase - Easy, sloppy, and not even that nice to look at.
JJ & Jeff - Most of us know the truth about this one by now, but back in the day, it received lots of praise in gaming mags, so I fell victim to the misconception that it would actually be good.
Spriggan mark 2 - Ugly despite the "effects." Blown away by geriatric SideArms, which has nicer music and better/tougher gameplay.
Andre Panza Kick Boxing - I've pretty much come to accept Panza for what it is and really don't mind it so much, but this is another one that I'd hoped would be awesome back when it was released, especially after it received high scores in VG&CE.
Emerald Dragon - It's a good game, mainly due to its music and graphics. But the hype that preceded my purchase of it was misleading. Its battle system has issues, and its plot lacks the sort of exciting moments that can be found in many other PCE RPGs. It didn't help any that right before playing ED I'd beaten Kabuki and Manji Maru, two legendary games that actually did live up to their billing.
Gradius II - This one was harder to find and more expensive a few years ago, so I had to wait a while before buying it, and all the positive reviews had me anticipating a real winner. Well, it's not bad, but by the time I played it, it felt so outdated and, for the most part, unexciting.
Sol Moonarge - "Just above average" doesn't cut it for an RPG that often goes for $40 on a system that has many truly classic RPGs for chump change.
Legend of Dekoboko - It looked so charming in screenshots, but the gameplay is awful.
Fang of Alnam - Looked promising from a distance, but it's just a so-so RPG that's actually pretty horrible aside from its cool battle system.
Ordyne - I dug the look of this game back in the day. Don't know what the hell I was thinking. Terrible graphics, terrible music, slow "action," poor game.
Iga Ninden Gaou - Trashy gameplay during the era that saw the likes of Shinobi III and Kaze Kiri.
Detana!! Twinbee - Not bad, but overrated. Nothing particularly good about it aside from nice, colorful background graphics.
Chiki Chiki Boys - Looked like good cartoony fun, but so stupidly easy that I beat it the first time I sat down with it, and unlike a Shubibinman 3, it ain't awesome enough to make up for the complete lack of challenge.
After Burner II - It's okay, and it has some really cool music, but there's hardly anything to it, and I expected a little more after reading some rave reviews. Space Harrier is much better.
Last Armageddon - Oh lord, I think I've already written a book complaining about this one. It was a huge success in Japan, and it was made by the same folks who produced Efera & Jiliora, a personal favorite of mine. I thought I was in for a treat. Oh, man... Painful.
