I'm still trying to get the last 20 points for the glitched 4th propaganda report. The game makes me physically sick (motion sickness I think) so I'm desperate to get it over with and put the game away and never play it again. It just infuriates me that I am missing one achievement - I've collected every metal piece at least twice - the first time round I missed one on level 7 (fell down a hole too early and couldn't get back for it) and I've redone that level at least twice, and all of the others too.
I am astonished at the ineptitude developers have shown with regards to achievements. A fair percentage of gamers (myself included) are hooked on the concept, whether for the glory of getting the individual achievements or for the overall pursuit of gamerscore, and yet it seems about half of the games out there have one or more broken or glitched achievements, or ones with ambiguous descriptions. Tiger Woods has two you can't get, PRG3 had one until recently, Joust, Robotron and Smash TV also have impossible ones, Zuma has two that take much longer to get than the description says, Condemned has two that are glitched - the list just goes on and on.
What infuriates me all the more is that as a software developer myself, it seems that coding these achievements should be the easiest things in the world to get right, and with all the breathtaking complexity of these games they can't get manage something as incredibly simple as counting thirty pieces of metal and calling some Microsoft API to unlock an achievement. I almost think it's a deliberate ploy to make us play the games longer than we otherwise would.
