Definately a perspective thing. MGS was and still is one of my favourite games ever and I bought a Gamecube a few years back just to play Twin Snakes. Some of the cutscenes are a bit silly, but some of them are much better, mostly anything with the Ninja. Some of the dialogue changes are a bit weak and the music in parts isnt as memorable. Overall though I prefer it because visually it fits with the rest of the series a bit better and the MGS2 controls and abilities are a bit easier to swallow.
I played Twin Snakes a matter of weeks ago and I find it really easy. I got all the way the warhead hangar before being spotted and setting of an alert. In the original game that would have killed me, but I slipped my gas mask on, hid in the back of the truck and eventually the alert faded and the room cleared of gas.
If youve got the patience because you loved the game the first time it doesnt feel that dated and its not that difficult. That first area in the game I never leave until they're all dead or knocked out. The helipad bit I always have to knock out the guy on the right side who's walking through the snow, and then I drag him to the edge of the cliff and throw him off through the gate. It's like a MGS OCD. I just have to do it.
