I can't understand how 95% of developers are clueless in what people who like trophies want out of them.
It's not that complicated. For games where the main attraction is single player, the platinum should be basically akin to "100%ing" the game.
Leave online trophies out. Or just have 2 or 3 that basically just have to try a few modes.
Don't add trophies that no one would normally ever do while attempting to 100% the game. Things like kill 1000x enemies with each weapon.
Don't make your most difficult trophies tied to minigames no one wants to play anyway.
In games longer than 20 hours, no missable trophies.
Avoid trophies that are almost impossible without an online guide.
Make me see everything worth seeing. Collect everything worth collecting. Again, basically just what we've always considered 100%ing the game.
