17:09 PST / 01:09 GMT (Phil): But there's more - in part two of the session, Jesse Divnich unveiled an analysis of achievements on Xbox 360, based on 32 million data points mined from Microsoft. From that data, 100 games were selected at random, and - with the caveat that generalisations shouldn't be made - there was some pretty unexpected results.

• Only 4% of consumers attain 100% of the achievements
• Less than 10% of consumers attain 80% or more achievements
• Only 27% of consumers get as far as 50% of achievements

In total, 21 per cent of consumers collected less than 10 per cent of achievements - the biggest single block in the breakdowns - while for triple-A games the 100 per cent completion rate is just 2 per cent.

"Does this mean achievements are too hard?" pondered Divnich, going on to pinpoint a general trend that - for core games - the higher the review score average, the more achievements were unlocked. Some food for thought for game designers, there.

Many are just too time consuming to even bother.
I have tons of games to play and I could never play them all if I tried to get 80% of all achievements.

Too time consuming to get them all. I would say i almsot have all the achievements on every halo game cause thats almost all i paly. Halo 3 odst 905. halo 3 1710 and halo wars 1150. need 50 on halo wars 95 on odst and 40 on halo 3 thats good enough for me and fable 2 is 1350/1350 cause single player achievemnts are much eisier than multiplayer and i like to explore everything.

3 things I think are the reasons;

*some are too difficult and people don't have the patience to work for it....
*some ask for so much time, people don't wanna spend so much time for just one achievement
*the achievements that require online play/gold membership and people who have silver accounts are screwed

I don't like achievements, they're making developers lazier. One of the reasons I've become a primarily PC gamer. My guess is that no one really cares, as much as X-box fanboys and the media say how amazing they are.

How are achievements making developers lazy?

@SmoothCriminal

how does achievements in any way make a developer lazy........that makes no sense whatsoever.

Also I think the biggest problem with alot of achievements is they just take so damn long to unlock some of them that its just not worth it.

Well most achievements are too hard, and should be easier.

I don't mind hard ones, it's the stupidly long ones that suck, like 10002 online kills and such.

They don't need to make the achievements any easier to earn.

It's completely up to the developer if they want to give players "point padder games" to boost scores, or just get them to rent the game if it's a weak game, or if they want to have players go for hours searching for an elusive, tiny achievement worth 5 or 10 points.

There's no real benefit for higher gamer scores, you don't have to unlock any points to see more out of your games.

As far as gaming specifically for individual achievements; it all depends on how much time you have to kill on a given game. The poll shows most people don't have the luxury of doing this for the vast majority of games, bought rented or otherwise played.
