I have around 40 hours in No Man's Sky and it was a blast. Had to concentrate on university for a few weeks, and that was the death of my playthrough. I tried a couple of times to continue, but yeah I just see 10 quests in my quest log and have no clue what I was doing before.

The thing is, I could totally relearn it again - but I already know I'll have to take a larger break again soon, so what's the point if I have to then put a bunch of relearning time in again the next time I want to play...
