Depends on the trophies or achievements I guess. I do like working on my PSN trophy level, so if there's an trophy that poses a reasonable challenge, I'll often go for it.|
If there are an excessive number of absurd multiplayer trophies ("win 100 online races" is always a classic) or grindy trophies though then I just don't bother going for 100%. Steam achievements interest me less as there is no overarching scoring system for it unlike PSN and LIVE.
