I'd guess 60-70+ hard saves at over 130 hours this game. I was hoping we'd have a thread about Saves as I'd like to hear other techniques for Skillful Saving. We've been having some posts where people have lost their game because they only had one Save or messed up their saves, etc.

Every so often, I'll use 7zip and archive off older saves in batches of 100 to clean up my save folder. And I'll copy special saves off into a sub-folder in case I ever want them down the road. Only takes about 5 minutes to archive off 100 save files on modern machines and it makes the save/load menu work faster as it's not trying to deal with 500+ saves.
But like you, I create a permanent save whenever I:
- Start sorting out inventory
- Finish sorting out inventory
- Before fast-traveling
- Multiple times during a particular dungeon crawl
- After important events
- Before what looks like important events
- After resting and refitting
- Every 15 minutes
- On a whim because the gecko ran across the road
FOMM used to have a save game manager, but it's not working yet in my copy of NVMM.
