Nowhere near that old. Maybe my age is why I don’t agree with a lot of opinions on this site?
I must agree with Dumbo that its story is a bit dull and its gameplay rather stiff.
That was precisely my point. Maybe you not growing up with the early-era videogames made you more critical of them since you've experienced games that have surpassed it on many, if not all, points. But you never experienced how Rayman 2 was a masterpiece for its time and that, in a time where videogame releases weren't as blindingly abundant as it is today, how much of an event it was.
Therefore, on the flip side, it could also be said that our love for those games are tainted by nostalgia, which can be a fair assessment to some degree. While it definitely did not aged as poorly as my next example, there are people who unironically believe that Goldeneye N64 still is a top of the range shooter.
What is objectively true about Rayman 2, though, is that it is the only game of the serie that has a whimsical-dark tone. No game in the serie since has attempted it.
And it's definitely a tone I cherish. But I most definitely wouldn't be against a remaster that irons out the gameplay, adds more combat variety and introduced more character arcs, which while still non-existent, Rayman 2 is still the only game to try and implement one (it's the only one where Rayman actually has a choice to make, in the cave of Bad Dreams, and you don't really have a choice anyway. That's how deep of a character arc Rayman underwent in the entire series)
