My beef with trophies is that devs seem to think that assigning the right color to a trophy is such a fucking problem. Really, few games do that right (Killzone 2 and Ratchet and Clank: A Crack in Time, for example).
But at least that's better than assholes who assign only one gold trophy to a game (inFAMOUS or Assassin's Creed 2) or make the hardest achievement worth 0 points.
And yeah, I agree, multiplayer achievements have to go. If it's a on-line based game, like Killzone 2, Bad Company or Modern Warfare, fine, no one buys those games solely for the singleplayer campaign. But stuff like the maximum on-line rank bullshit in GTA4 is a Goddamn crime. It has one of the lowest achievement rates here on Giant Bomb. Hell, I dare someone to find a bigger turd here. And it's perfectly logical why that one is so rare - the multiplayer component is mediocre at best, it's filled with cretins who can't even get past the lobby screen (because changing your team color every second to achieve a rainbow effect is so entertaining) and probably dead by now (because I refuse to count those rainbow fuckers as human beings).
Also, I hate DLC achievements that aren't separated into a subcategory, therefore robbing someone of their S-Rank. No one should be forced to buy DLC if he doesn't want to, he can and should be persuaded though ("10 MORE 'CHIEVOS BABY FOR 15$" is fine by me). I perfectly understand someone who doesn't want to buy Mad Moxxi's Underdome Riot for Borderlands, even if he bought General Knoxx and The Zombie Island. Because the realization of the Underdome's general idea in that DLC fucking blows.
I don't have a single S-ranked game, so neener neener!
Grats on getting platinum though ;P
