Zing!
No, MGS 2 and 3 were on PS2, tho both are in the PS360 hd collection. You're thinking of MGS4. That's PS3 only, and actually the only Metal Gear Solid that never got ported.
That's right. I played MGS3 on the HD/Legacy collection(whichever one has most of the games on it) on the PS3. Which makes me sad it hasn't been ported to PC or PS4(or even PS5).
I think I'm just salty that my favorite MGS game is basically dependent on my PS3 holding up enough for me to be able to play the collection I have, because while I can play MGS1 and MGS2 on PC, I can't play MGS3 because apparently nobody thought it was important enough to port forward to a newer, less dead and finickly console.
Either that or I take my chances with emulating the Collection on a PS3 Emulator.
