looks better, plays better, skips the backtracking in the metal gear hangar. Has more logical/less racist voice acting (that they continued for the rest of the series with the characters that returned) and besides switching the great boss battle theme with shittier individual boss themes it has a better audio mix and track selection.
- Looks better? Whatever, I still like the dirty pixelated MGS1 artstyle, but I'll give you this.
- Plays better? Meh, plays
newer, but most of the MGS2 mechanics are superfluous anyway. If we're being honest, 1, 2, and 3 all feel old no matter what version you're playing.
- Skips backtracking. Meh, MGS1 was a classic with backtracking. Removing it doesn't really make a difference.
- Better voice voice acting? MGS1 Snake is the best David Hayter performance. That outranks stereotypical accents.
- Better audio mix? In terms of sound effects, sure
- Better track selection? Last time I saw an MGS1 vs. TTS comparison, MGS1 sounded way moodier. I much preferred that soundtrack.
In the end, I just don't see a good reason to recommend Twin Snakes over the original. Solid Snake becoming a superhero in certain cutscenes is the icing on the "WHY" cake. Notice I never said it's a bad game, just that there's no reason for its existence.
