How to get into MGS again?

Basically, I want to replay MGS games again, to remind myself of the story and finally beat PW and MGS4. But I just can't force myself to play those games again. Mostly MGS4 and PW exactly. PW feels a bit too old for me, and MGS4... Well, my PS3 doesn't work so well anymore, and I cannot really emulate it on PC because of too weak CPU. Any tips how to get into this series again?
