Gameplay-wise:
1. MGS 2
2. MGS
3. MGS3
4. MGS PO
Explanation: MGS 2 brought many new things to the table over the original MGS gameplay wise. Once Splinter Cell was created though, the MGS gameplay started to look like Resident Evil tank controls in comparison.
Story-wise:
1. MGS
2. MGS 3
3. MGS 2
4. MGS PO
Explanation: MGS set-up the way they tell stories, so each iteration in comparison was a bit more expected to be crazy, slightly taking away from it. Kinda like M. Night Shyamalamdingdong pulling the same tricks each movie he creates, weakening the surprises in each. MGS 3 over MGS2 just because it veered a little more back into a semi-reality.
Overall:
1. MGS=10/10
2. MGS 2=9.5/10
3. MGS 3=9/10
4. MGS PO=8/10
