@Cakemagic I completely agree that not all can be re-achievable. One even easier to farm than falling from the top of the lobby is talking to the condo lady drunk, which obviously cannot be re-achievable in any sense as it is easy to do a great many times in a ludicrously short time span.
@xSkyer I actually do like that tiered system, especially with @Sapphire’s idea of some grand reward at the end (so long as it is not ridiculous to achieve). Perhaps beyond the final goal, my original idea could be in place, or perhaps that would be it and the achievement could no longer be re-achieved.
I just thought it might be a nice way to continue earning small amounts for repeatedly good performance in gamemodes or continually partaking in generally unpaid activities (perhaps some alternative to this suggestion). Again, my system would pay out very little compared to other things, but it would be a nice, little bonus every now and again.
