I'm not sure what the opposite of an achievement is, but the gaming industry has certainly reached one with their willy-nilly adding of 'achievements' into every game released these days.
This fellow is suggesting that achievements are the best thing since sliced bread and can be added to most any game of any sort in any way to make it more fun.
I can not begin to express what pure essence of fail that sentiment is. 'Achievements' in their standard implementation are awful game design, rewarding idiotic tasks that every single player will achieve, usually accidentally while failing at the actual game itself. They're not fun, instead bringing out some obsessive-compulsive-addictive, completely ugly side of all of us.
That's not to say that achievements couldn't be fun in certain ways. I for one used to set goals for myself in games long before achievements became popular - complete on the hardest difficulty, without dying, with weak characters, solo, without anything beyond the basic weapons, etc - the purpose of this was to challenge myself, since overcoming the challenges was fun. There are a precious few achievements similar to those I've listed above in modern games. The other 95% are meaningless drivel that present absolutely no challenge and just aren't fun.
Cardinal rule of game design #38: if the achievement can eventually be obtained by a blindfolded monkey mashing the keyboard/mouse/controller, it's a crap achievement. Bad, bad developer, now go and stand in the corner.
