My list
1) Galaxian. i think i speak for a lot of people when i say BLAH! GO play galaga instead.
2) metal slug games. I'm sorry, i just cant' get over the slow framerate present in every metal slug I've ever seen. This s supposed to be the pinnacle of wallkabout shooter design???
3) Robotron X. Frameskipping BAD, mmkay? That alone kills the game for me.
3) Metroid 2. This has not aged well. The first one was still brilliant, though.
4) Dracula X for turbo duo. Everyone says it's the best castlevania ever made, and while it's not a bad game, I just don't see it.
5) Any mortal Kombat. I know I'm not alone here.
6) Klax. It's a fun enough game for a bit, but it seems to have too much of a luck factor, and the way the difficulty ramps up so fast boggles me. I'e never seen a klax master. I've seen peopel tear up Colums even tho I suck at it, so I know it can be doen but never klaxx.
7) Tetris Attack. puzzle mode was fun, bt that's about it...

Double Dragon. I'm sorry, but the final castle level is just cheap with the spears and blocks. And other than that, you just elbow your way thru it. this is supposed to be one of the best beat-em-ups ever??? Oh, and wayy too much slowdown...
9) Gauntlet and gautlet II. Gauntlet 1 is incredibly dull, and while gauntlet II is actually more intereting, this is tempered by it's cheapness with depriving you of food when you score enough points. Sad thing is, with all it's bugs, the NES version f gauntlet is actually an IMPROVEMENT over both arcade games. Yes, a while ago i used to think gauntlet and gauntlet II were so cool, but emulation has revealed how mind-numbing dul they actually are, and how little true stratey is required for them.
10) Magic Sword. I'm sorry, i don't know what everyone sees in this game. even more mid-numbingly boring than Gauntlet 1.
11) Dragon's Lair. All graphics, and no gameplay. Truly ahead of it's time, Still as the first of it's kind, it has it's place...
12) Comix Zone. oooh, cool, someone pencils in an enemy and it comes to life. lets go beat it up. What? Game ove ralready, an dno continue? How am i supposed to have fun with this thing? It looks liek it's supposed to be an epic game, but I die too soon to have fun.
13) Defender/Stargate. I'm sorry, I have to agree on control complexity for control complexity's sake. WHY WHY WHY??? one joystick, thre buttoms. all you needed. no, they have to tack on thrust and reverse! Controls should be ter eto help you play the game, not inconvenience you.
14) Phoenix. I'm sorry, that game is ruined by it's crappy hardware. would actually be fun if parts weren't so jerky.
15) Tempest. While it was really trippy back in the day, it has NOT aged well. Tempest 2000, despite a few niggles i have wit hit is much better, and brings it's trippiness up to date.
