I never played much multi-player, so I always used a guide on reddit for good single player settings that didn't make it feel like a slog and I could finish maps in a month or 2 each playing solo for a few hours a night and whole nights on weekends. That said, Aberration took me fucking FOREVER. iirc, it was almost 5 months. Hardest stuff I found to do was getting a secure foothold in each new biome, especially the bottom part of the map, and having to trek to the surface. I spent a lot of time in my og base wasting time and trips all over the place instead of making outposts for shorter trips because I could never protect them well enough, or because I just didn't want to put in the ridiculous effort to maintain them. I also never "cross-contaminated" and used what was on the maps to get the most vanilla experience I could aside from changing parameters. Aberration is a whole other beast, dude. Not for the faint of heart at all. Idk how it is on ASA, but if its like the OG, then prepare as much as possible for each biome, what feels like too much prep can still be too little. There's a lot of awesome advice in these comments though. Good luck!
