I have 0 platinums. I refuse to go beyond the point of having fun to get a trophy. If it looks like a fun, interesting challenge then I'll try it out. If it looks like a chore then I'll pass
Since plats usually require you to get all other trophies, it seems like too much of a grind to be any fun. If I get one just playing the game as I normally would, cool. If not, I'm not exactly missing out, either.
Now, If getting a plat unlocked some sort of additional content or ending, or otherwise had an actual non-epeen incentive? Maybe then.
