What's the worst port you have ever played? On which system did you play it? Why was it so bad? Was the original game good to begin with?

The worst port I have ever played was Myst for the 3DS. It was really cheap and I haven't played Myst yet (and I still haven't) so I bought it. Right of the bat, you have two screens, one for the map of the island, one for the actual screen. The real game is on the upper screen, while the map is on the touchscreen. The original game is on PC, it used a mouse, it would have made sense to put that on the touchscreen to replace the mouse. You have to move the arrow with the circlepad, and it's slow and irresponsive. The map on the touchscreen is pointless, it does nothing. I don't want to complain about the graphics, but they are awful, even if the game wasn't a visual wonder to begin with. The worst for me was the reading sections. I have a regular 3DS, not a XL model. The full text occupies one screen, you can't expand it and you can't put an option to listen to it. It hurts my vision, it can't be read. I abandoned the game ten minutes after I started. Don't touch that game, just get it for PC where it was meant to be. Myst 3DS isn't worth the 9€ it cost me.

Street Fighter II on DOS.

Any Mortal Kombat on Game Boy.

By all means, this is something that should be played on PC. As a P&C adventure fan, I'd even say preferably with someone else, it's much more fun playing these puzzle-solving FPP adventures together.

Oh, and do play it, it's a great game (if you like the genre) and Riven, its sequel, is arguably still the best adventure of that type to this day.

That awful Dead Rising port for Wii.

The Operative - No One Lives Forever on PS2, because they removed the save game feature and the game became unplayable at certain point. The visual downgrade also was very significant.

Call of Duty 4: Modern Warfare on Wii.

That port almost made me gag.

Sleeping Dogs ps4. Crash on me once, restart it and threw me a few mission back.

Hmm...do I go with Pac-Man on the Atarii? Street Fighter 2 on Gameboy? Diablo on PS1? Silent Hill 2 HD?

Think I'll go for the one that vexes me the most, Final Fantasy Tactics on PSP. Glorious additions, beautiful new translation...and some bizarrely bad slowdown for every combat action. I want to play it on my PSTV, but I just can't do it.

AC Unity on PC. On console it's Skyrim on PS3.

Diablo 1 on ps1 is quite good, they added reflection effects and playing with a controller makes lots of fun
