Plat Ain't It, Chief
Oh hey there! A while back a bunch of us content-creating site folk wrote up a list of our "S-Ranks": those games that we've completed in their entirety, to the extent that we've earned the coveted Platinum Trophy (PlayStation), 1000 GamerScore (Xbox), or a cute if patronizing "well done, you" message (Steam). However, there are many more games out there where I've earned almost every achievement/trophy going... bar a scant few. Those near-misses are what this list is about.
Let me tell you how my broken brain works w/r/t trophies: I'll take a glance at the list first and a roadmap of how much grinding/subsequent playthroughs are involved. If there's too much busywork, I'll flake on collecting them then and there and just enjoy the game like a normal person. However, if I'm about 80%-90% the way to a Platinum, my OCD will kick in and I'll look to complete the rest regardless of what's involved. There's only been a few cases where those final elusive few trophies prove too much, and I leave the game in a slightly uneasy mood: it's honestly better for me if either half the trophy list is insane and I can skip it all or if it's all attainable in a single playthrough with a moderate amount of challenge.
To an extent, these games left a sour taste in my mouth, though only because I have some very dubious brain chemistry working against me. Achievement design is a tricky process that's still in its nascence, so I don't begrudge the majority of the following games for their occasional clunkers. Mostly.
