10 Rarest Xbox Achievements

Rarity: 0.01%

With how surprisingly prolific most driving sim games actually are - and how committed their fanbase often is - the only thing unusual about the Leipzig Legend achievement.

Getting it is admittedly a big ask, though, as it requires you to complete every available service in the Rapid Transport DLC - which involves sixty four separate journeys.

As if that wasn't conceptually harrowing enough, some of these services take up to an hour and a half to complete - which is a long damn time when you're painfully aware you have another sixty three left to go.

Admittedly, there are ways around this - as the resourceful Train Sim forums have found a way to finish a service without having to sit through the whole thing. But unless you were specifically scouring the internet for a way to do this, you wouldn't know - and so you can bet real money on the fact that of the scarce few who've finished this, some did it legit.

However, the forums are important in other sense, in that they raise the fact that this achievement can also bug out on you, meaning you've potentially just driven over fifty trains for absolutely zilch.
