Yeah, MGS is pretty famous for that
I like it, just because I like a good story. You would've hated MGS2 probably. I will admit, that one got pretty convoluted with the message it was trying to convey.
I grew up on MGS1 watching my dad play it, and I picked it up. Then I got 2, and it got me hooked. 3 is tied with 1 as my favorite, as the story isn't so hard to comprehend, yet delivers a great message, and the gameplay is amazing.
I'd recommend 3 if you want to get into the series. Probably holds up to more modern standards these days.
