Here's my own personal list::
#10. Defender - Atari 2600 ( the fact that they couldnt figure out a way for your ship and your shots to be onscreen at the same time says a lot for the quality of this translation. It didn't even remotely look like Defender graphics-wise. I mean, they could've at least TRIED.)
#9. Rough Ranger - Arcade (Just play it, and you'll believe me. Un-fun)
#8. Way of the Warrior - 3D0 (The only good thing about this game was the soundtrack. bad control, bad acting, really bad motion capture - what, did this game have like 5 frames of animation for the characters each? Stolen story and concept for the Necrocomicron Book of the Dead from the Evil Dead movies...)
#7. Street Fighter - Arcade (The most horrible control of any fighting game known to man. The jump in quality from this to Street Fighter II was like the jump cut you see in the movie 2001, when the ape throws the bone up into the air, and the next scene is of a space station in orbit around the Earth. Seriously)
#6. Platoon - NES 8-bit (I actually feel my will to live drain away when I play this game)
#5. Laser Blast - Atari 2600 (The most repetitive game I have ever, EVER had the misfortune of playing when I was a kid)
#4. Reactor - Arcade/Atari 2600 (Completely devoid of fun on ANY level)
#3. Home Run - Atari 2600 (Unfiltered ass-in-a-cart is what this steamer was. I actually owned this POS..._
#2. E.T. The Extraterrestrial - Atari 2600 (It just sucked. If I was a bug tester in the the 80's I would've written up a bug like this: Bug - GAME NOT FUN Solution - MAKE GAME FUN)
#1. Pac Man - Atari 2600 (this translation was so bad. Pac Man could only face one direction, flickering ghosts, that irritating "Dan-Dan-Dan" sound when you ate pellets, the fact that trying to navigate into the portals on the top and bottom of the screen was near impossible, but the most amazing thing about the this game is HOW OFTEN THE PAC MAN DEATH SOUND FOR THE ATARI 2600 VERSION IS MORE CLOSELY ASSOCIATED AS THE ALL TIME GENERIC "VIDEO GAME" SOUND THAN ANY OTHER VIDEO GAME SOUND!!! You hear it in movies, in comercials, for crap that doesn't even have anything to DO with video games!)
