Achievement frustration.

I admit, I love the concept of Achievements (Trophies, Badges, whatever your games may call them) because, if done right, they reward skill and time invested in a game.

However, what I absolutely loathe are achievements that are tied to randomness, meaning skill doesn't play a factor at all, rather you have to be lucky to earn them.

An example would be Geometry Wars Evolved 2, where there are three achievements tied to completely random events: Wax Off, Rebound and Treaty.

For the Wax Off achievement, which requires you to run along the edge of the playable plane twice in Pacifism mode, you have to be lucky with the enemy spawns. Will enemies spawn in this corner or that corner? Will a gate spawn along the edge of the plane? Will a cluster of gates spawn and make it near impossible to move through a certain section of the plane (the orange tips will kill you like any other enemy and they wobble back and forth).

For the Rebound achievement, you have to kill 75 enemies by rebounding shots off of gates in Deadline mode (3 minutes timed). Will a gate even spawn? I've had whole games where I didn't see a single gate and then others where I'd see four or five gates.

For the Treaty achievement, you have to activate 30 safe zones in King mode without firing a single shot or destroying an enemy with your shields at the start. Like Wax Off, this relies completely on where things spawn and becomes troublesome after you've activated 25 and the diamond enemies speed up. Will the next safe zone spawn nearby, or will it spawn across the map (which you'll never reach because the diamonds speed up to the point of being able to catch up to you even if you're doing a straight line)?

Achievements that are tied to completely random occurances aren't really Achievements.
You don't "achieve" luck, it's just something that happens.

If you've managed to get these Achievements, congrats! I wish I had your luck.
