You can't even play mgs hd collection on pc or ps4. Hell if you want to play on pc there is mgs1 and 2 on steam/gog (its the original versions not the hd collection ver), but no mgs3 and nothing on ps4/5. The whole thing plus peacewalker is locked on ps3/vita and nothing we can do about it, sadly.Because Konami.
Konami is horrible anymore. They have all my favorite series and aren't making anything or porting anything.
Suikoden 1-5 + tactics
Castlevania series (well they did do sotn but not on switch, the collection and gba games did come out though).
MGS -all of it can't play on ps4/5
Silent Hill - haven't made a game since downpour on ps3, and none of them ported to ps4/5. PC has sh1,2,3, the room and homecoming, The rest require ps3 for the collection and psp or wii for shattered memories.
Retro games like Contra and lifeforce they have made collections for.
Konmai needs to port this stuff. WTF!
