I've finished my playthrough of MGS2, and since I was using the V's fix version of the PC port, I feel it's perfectly acceptable.
However, The video cutscenes wound up broken after a while and froze on certain images. Oh, well. All the more reason why a PlayStation 3 is the best platform to play most of the Metal Gear games on!
Oh, and I'm now off to play Metal Gear Solid 4: Guns of the Patriots. Yes, after Solid 2, it's basically choose your own adventure; you can go forward in time to wrap up Solid Snake's story and end the Patriots once and for all in Solid 4 and find out what happened to Raiden and other characters after Solid 4 in the actionized spin-off/epilogue Metal Gear Rising: Revengeance, or you could go back in time with the more comedic 60s spy homage Metal Gear Solid 3: Snake Eater and discover the origins of Big Boss. I chose the former to see what becomes of everyone now that the Patriots and their AIs are ready to enact their plans for global domination, and also because I had a pretty bad first time with Solid 3.
I know that from Solid 3 onwards, you have to think like a predator, so we'll see how this playthrough goes.
Back again. Just want to tell you that not only am I slowly adapting to the predatorial gameplay, but Solid 4 is fantastic. It's probably much better and more refined than Solid 3 (from what I remember), and in terms of the "Patriots Storyline" (aka. Solid 1, 2 and 4) 4 is probably the second best behind 2 and above 1. I mean, the bunker section in the first act/Middle east section is just so much fun, picking off enemies with your rightfully acquired Silenced Operator and Tranq Gun and avoiding others.
Also, OctoCamo is the best addition to the post-Solid 3 gameplay formula.
