When a game becomes a hit, it's not uncommon for it to see releases on other platforms. If handled with care and attention, ports of games can address problems fans and critics had with the initial release. They can even introduce a brand new audience to a beloved title that they would otherwise not have been able to experience.
Unfortunately, it doesn't always work out this way. Several factors can result in a bad port: maybe the hardware just wasn't powerful enough to handle it, maybe the developers had little to no time or resources to properly optimize it, or maybe the publishers just outsourced it to some cowboys who didn't care about/know what they were doing. Whatever the reason, if you plan on trying out any of these classic titles, just make sure that it's none of these versions.
'Shadow of Mordor' (PlayStation 3 and Xbox 360 version)
"Shadow of Mordor" provided a well-needed shot in the arm to the all too familiar open world genre. That was provided that you played the versions on PlayStation 4, Xbox One and PC. Gamers found out the hard way that one does not simply walk into Mordor with last gen consoles. Predictably, the draw distance, frame-rate, and polygon count took a hit on less advanced hardware, but the most grievous omission was the Nemesis system that made the original version stand out.
'Silent Hill HD Collection'
"Silent Hill 2" and "Silent Hill 3" were initially released on the PlayStation 2 and are well renowned for their psychological horror and unforgettable monsters. The versions for PlayStation 3 and Xbox 360 turned out to be an absolute nightmare for all the wrong reasons. Fans who dare venture forth this collection will have to brave inconsistent frame-rates, audio glitches, and the lack of the series' trademark fog exposing parts of the environment that were never meant to be seen.
