To me achievements make more sense when you count the community aspect. They can be humorous or motivating while playing standalone, but usually games have their own ways of providing a sense of progression and achievement (or they will be boring!). Achievements become really interesting when you compare them against the community, and you can find extra motivation in "oh, only 10% of the players have managed to do this, lets go for it!". Further development ideas for retrophies inclued building on this community aspect. Although now that I've discovered retroachievements.org I'm not sure it's worth the duplicated effort :P
