After tuning up my plumbot to future tech, installed sentience and made friendship with him, my plumbot rolled a LTW wish to become super popular.
Perhaps other LTWs will pop up if I install chips like evil or romantic ones and trigger different situations, but I guess like child/teen, they should be able to roll these LTW wishes for you to decide whether to grant it or not?
I still don't know about opportunities though, I've had him with sentience for only a few hours.
