TF2: Milestones
I said that I’d consider Team Fortress 2 to be off the Stack when I had spent a significant amount of time playing every class. At this point, I’m tentatively declaring a less vague criterion: getting the first Achievement milestone with every class.
These milestones are Achievements that are awarded for getting a certain number of class-specific Achievements — the key numbers are 10, 16, and 22 for most classes, except the Sniper and Spy, which get them at 5, 11, and 17. At any rate, there always seem to be three milestones. Looking at the Achievements, it strikes me that they’re also easily divisible into three categories. First, there are the ones that are likely to happen eventually regardless of whether you’re specifically trying to make them happen or not — for example, the Pryo achievement which simply requires you to kill 3 enemies in a row in the same area, or the Scout achievement for running 25 kilometers. Secondly, there are the ones that are unlikely to happen naturally, but which you can deliberately pursue, such as the Sniper achievement for getting 5 kills with the Sniper Rifle without using the scope, or the Medic achievement for cooperating with two other Medics to deploy three simultaneous Übercharges. Thirdly, there are ones based on unlikely occurrences that are completely beyond your control (unless perhaps you have someone on the opposing team cooperating with you), such as the Medic achievement for deploying an Übercharge on someone less than a second before they’re hit by a critical explosive. To a certain frame of mind, only the second sort are really deserving of the name “Achievement”, but I’m willing to accept it as a term of art.
It’s debatable which of these categories a particular Achievement belongs in, but looking at the list, it’s pretty clear that the majority of them are in the first category — certainly more than enough to clear the first milestone. So really, if I keep on this daily lunchtime regimen, it’s only a matter of time before I meet my goal. Except for one thing: Two Three classes, the Demoman and Engineer [EDIT: Also the Soldier], don’t have mission packs yet! By complete coincidence, these are also my two least-played classes. I expect I’ll give them a larger try when their class-specific content is released.
