Let's break it down!
Alpha Mission 2: Good game, crazy system, feels odd but patience is a virtue, the game is awesome!
Andro Dunos: Great game, options galore, kinda reminds me of gradius meets R-type with SectionZ art style.
Art of Fighting: Good game, stiff mother of all stiff mothers but it's the evolution of SF1, it's only natural to be curious, great atmosphere.
Baseball Stars: Good game, very plain jane palette and sprite work but I think it's got that classic look in purpose, simpler commands make for a more intuitive play over its successor.
Burning Fight: Mediocre game, it does what is supposed to ok for the naked eye, not my cup of tea, never really cared for it. From day one it always looked cheesie.
Eight Man: Good game, plays great, looks awesome...how can you not like this game?!
Ghost Pilots: Mediocre game, it plays well enough but it's so slow, it's not as bad as lots of shooters of the time.
Legend of Success Joe: Bad game, we all know this. One thing though, the control scheme could have been used as a basis for a real fun brawler with Boxing controls, maybe a character in a game or just the game in general. The Neo could have used a decent boxing game.
Magician Lord: Great game, Hard to get into, not friendly at all but once you get it, it's great!
Ninja Combat: Mediocre game, although it does move well the game just reeks of lame somehow, I dunno, maybe something eludes me but I can play it once every 5 years and get my fill.
Puzzled: Mediocre game, I wanna like it so much 'cause I'm a Tetris whore but as much as I like Tetris Plus, the system here is meh, the difficulty ramps up extremely fast, I can go for a while but there's not much keeping you hooked and then the funky levels with more shit than ever, it's too much, a shame really, game could have been great.
Robo Army: Mediocre game, another game that looks great but it's a bit underwhelming, perhaps is the insane look, it looks far more complicated than it actually is, doesn't make it a bad game, the game plays well enough, a decent challenge too so I can see some folks getting into it.
Sengoku: Good game, simply 'cause of its originality, it plays like KOD and people are expecting it to play like a brawler, it is a brawler but it plays like an even earlier brawler.
Super Sidekicks: Good game, just 'cause each iteration got better and better (well that could be argued with U11) doesn't mean the first one is not a good game.
The Super Spy: Mediocre game, I'm sure some folks love this game, I for one don't really care for it much, not for lack of trying but it's really too bland to keep me hooked.
Top Players Golf: Good game, good controls, hard as hell, a good change of pace from Dat Turfies Life.
World Heroes: Good game, controls better than many clones at the time, same thing, just 'cause the sequels got better with time doesn't make the 1st a bad game.
SO there's only one game that I can say it's bad, all the games in this list are prolly the common denominator for a lot of people, but some of the games always had a stigma, like Super Spy, it has always been avoided for the most part and the same goes for many. The thing is some of the games are actually really good, you just don't know what to label them, you don't like them, I get it but aged badly, it's kinda dumb, some of this games always look bad, some got better with age, others never looked bad, so I dunno man, keep playing what you like I guess.
