The Steam achievement in Darkchaser is quite interesting—one of them requires you to travel the distance equivalent to circling the Earth once, and another requires the distance from the Earth to the Moon. However, I still want to complain: is anyone actually able to complete this? I know it's a game that requires you to run around all the time, and I've already played for 100 hours, but it's still far from enough :D
If you were traveling at a constant 100 mph, it would take you 249 hours to travel around the circumference of the Earth, and 2,389 hours to reach the Moon. If the distances are actually accurate then these achievements should be nigh on impossible to get in any reasonable amount of time. That now 0.2% of players have them means the distances aren't accurate, that they used an achievement unlocker, cheated in-game, or have a fuckton of playtime.
My money's on stick binding and leaving it for days.
Never underestimate the "fuckton of playtime" option. Some people just get really into a game.
