I like how great achievements aren't hard to think of, and yet there's probably someone on the team that gets paid to do so, and makes them shit.
If you want bad trophies, look no further than Socom Confrontation.
My least favourite is the BFBC2 multiplayer one. Most of the trophies are pretty cool, but there's one called demolition man, where you have to kill 20 people by collapsing buildings onto the heads of enemies. It's bloody hard trying to force this, and I gave up for a few months just thinking it'd get completed itself.
I've played online tons, and always use RPGs etc, and through natural play for days worth I racked up 5. Why did they make the number 20?! It's so frickin' difficult. You just don't go in buildings with only a couple of walls left, plus, if they're coming down, there's a sound that telegraphs the event to all of those in danger, so you virtually have to be a retard to not escape.
However, over the past few days I've somehow managed to get 10 of these kills, bringing my total to 17, and even a couple of those somehow cropped up from glitches. Hunting for this trophy comes at the expense of any enjoyment, because you have to use a crummy class setup to make the task 'easy' to do. It's just a fucking piss take. You get raped in your attempts and there's a high chance that a couple hours of work at it will be fruitless.
Every other trophy was done months ago, this one has just been festering, preventing me from that juicy platinum.
Oh yeah, a kind of rubbish/insanely hard trophy:
Complete Mega Man 10 without losing a single point of damage.
You'd think you'd get 5 billion platinums for doing that.
No. Just a silver.
