Sequels to titles in the Final Fantasy main-line series used to be non-existent, so when a direct sequel to Final Fantasy X on the Playstation 2 was announced there was no small amount of interest from players at the time. I personally picked up ‘Unlimited Saga’ largely for the bonus disc with the ‘linking’ short animation they included with that game. To say that people were intrigued with what could happen AFTER the world had been saved was putting it mildly.
DC Universe Online sets itself in the ‘old’ DCU as seen in the comics prior to Flashpoint and the advent of the New 52. If none of those things mean anything to you it summarises easily as ‘Superman wears his traditional costume and Wally West is still a red-headed Flash’. For people of my age that means a lot because ‘my’ DCU doesn’t exist anywhere else any more.
Final Fantasy VII was a watershed moment for JRPGs in the western world. For a long time they had been considered niche and unpopular as a genre outside of Japan, with SquareEnix choosing to stilt the releases of their flagship series because of it, leading to a renumbering of FF6 to FF3, and FF4 being turned into FF2. Final Fantasy VII would change all of that, and upon its release everybody began to ask where these other titles they’d missed had been hiding.
