Games need separate platinum trophies for single player and multiplayer.

No. Platinums do not exist to give you a pretty graphic on your trophycard. Platinums exist to keep you playing for a long time- they give you an incentive to do so.

So there should be one platinum per game. The whole POINT is that it is hard to get. If you don't want to play the game fully to get the pretty graphic, that's your loss.

You or anybody else still hasn't addressed the issue of how you think games with dead online components should be handled.  What if I actually want to play online, but can't find any matches?

Tough.

If you can't play online, you can't play online. The only difference between what you are proposing and what currently exists is that in the circumstance you are describing, you still get a pretty graphic.
