>I just spoiled myself on MGS 2 to 5
I wonder how, and what do you think you know.

That being said, MGS is a truly epic, fascinating saga, that is also a joy to play. (You)r input, you overcoming the challenges, play as big part in the Metal Gear experience as the "plot" itself.
There's also plenty of curious subtext that may truly make you think about life.

Not only that, but I find Kojima to be one of the few people on the industry that dare to challenge the (fundamentally American) black & white "good vs evil" tropes. The series is full of characters practically working towards the same goal, but with completely different means and priorities, resulting friction between the factions and friends alike that may escalate.

tl;dr: go and play the original MGS1, and see for yourself whether you can get behind the series' vibes.
