achievements: replace eternium man with something that does not require scripting
One of the achievements you can unlock is "eternium man": achieve level 50 in the SMC without visiting other locations.
In my opinion this is not a good challenge for an achievement. It has been achieved, but only by using a script. And scripting (as opposed to actually playing the game) is the only way it can be done. You need to set up a automated pickpocketing factory and let it run for many thousands of turns. You can hardly do that by hand.
Therefore I would propose to replace this achievement with something that's possible to achieve by actually playing the game.. if a really difficult achievement is needed, there are many better alternatives.
For example, Brimstone man (killing the ACW without visiting any other place than the ToEF) would be a good one. This has been achieved a few times (so it's proven to be possible), requires a lot of skill and persistance, and does not involve any scripting.
But there are other possibilities, too. Anything is better than eternium man.
