When I look at achievements, some of them have additional symbols next to the "achievement points".
I know the 10 is the number of "points" (though I have no idea what those points are for). But what do the cross symbol and the star with the 2 next to it mean?
Best Answer
means that the achievement has 6 rewards for completeing its various stages.
Is the collapsed/expanded state of the achievement. If this icon is absent, the achievement cannot be expanded.
means that this achievement is worth 10 points.
Achievement "Points" are an arbitrary number by which you can measure your awesomeness. Nearly all achievements are worth 10 points, regardless of their difficulty.
The one notable exception to this rule is "meta-achievements", the criteria for which are to complete a group of other achievements that are typically related to one another. These are usually worth more than 10 points.
