Questions & Answers about Avevo un amico immaginario che viveva qui.
Is this an example of the imperfetto ludico (play imperfect) since it talks about an imaginary friend?
Strictly speaking, no. Even though the topic is imagination, avevo and viveva here are just the standard descriptive imperfect used for ongoing past states (I used to have...). The imperfetto ludico is used to create a simulated reality for a game, often substituting the present tense, like a child saying io ero il drago e tu scappavi (I am the dragon and you run away).
Why use the imperfect viveva instead of the passato prossimo ha vissuto?
The imperfect is required here because it describes an ongoing background state in the past. The friend living there did not happen just once or for a strictly defined, completed period; it was a continuous reality during your childhood.
Could I put the adjective before the noun and say immaginario amico?
Is there any difference between using qui or qua at the end of this sentence?
In this context, they are perfectly interchangeable. Qui often implies a slightly more precise spot (right here in this spot), while qua can feel a bit broader (around here), but for an imaginary friend living in your house or room, either word works naturally.
