Thank you!
This makes so much more sense. And will help people who play medieval hoods as well!

Mr. Humble already appears to be selective, although I have no idea what the selection criteria are.
What I mean is that over the course of time and the testing many of many of my Lots, I've observed that Mr. Humble never seems to deliver a computer if I use the Picaso couple for testing a Lot.
I have no idea whether there are other Maxis Sims that don't get the free computer, or whether this exception could also apply to player-created Sims.
As an aside, guirnaldas, can you shed any light on why Mr. Humble never visits the Picaso couple?

There's really no criteria regarding sims at all, he simply shows up to new families moving into neighborhood or pre-made families. Since the Picaso are premade they should receive the gift within few minutes playing with them for the first time. In your case maybe they've already received the gift before and either sold it, deleted it, or left it behind when they moved to another house.

I use the Picaso couple to test Lots without saving after a test. I suppose there's a remote chance that at some point I made have "Saved" them after a Lot test for some odd reason, but I typically don't. They are not the only premades I use for testing Lots, yet they seem to be unique in not getting a free computer from the Humble Guy.
Anyway, not your problem and not a big deal, I just thought maybe you might be able to shed some light on this. There are so many ins-and-outs to this game that it's often impossible to determine things with any certainty.
Thanks for your answer.

No problem, I just checked the Picaso couple in my game and they do get the gift. Try it on a fresh neighborhood.

The nohumble mod has been in my game since the very beginning, but I might just get rid of it in favour of your mod.
Cause that makes Humble's PC feel more like a reward, and not like free money just for existing.

Small request though, is it possible to make a combined version that includes all of these criteria? IMO they all make sense in their own way.

I think that would turn this into an extremely tedious task to complete [?], and a lot of things to remember. Actually, maybe the career version was a little too much, given that the prize is worth only 1350 simoleons after all :P
