To have ''Idle each game individually'' or ''Idle games with more than 2 hours individually, then simultaneously'' ? Thanks in advance :)

Do you mean "LESS than 2 hours"?

Depends on the account. If you get drops with less than 2 hours of playtime, then "each game individually" is optimal. If your account requires 2 hours of playtime before drops start, idling all games up to 2 hours simultaneously and then each game individually is better.

Nope, in the options it clearly says ''Idle games with MORE than 2 hours individually, then simultaneously'', go to File > Settings > Idling behaviour and youll see it as a third option. Based on what does Steam evaulate if my account should drop cards before 2 hours or after? Cuz I noticed that Ive been receiving cards with less than 2 hours, so, thoughts?

If you are receiving cards prior to the two-hour mark, idle games individually. The other settings pertain to those accounts that require a minimum of two hours for each game before cards start dropping.

(The only speculations that seem to be believable about the cause for different drop algorithms for different accounts revolve around whether refunds have been granted in those accounts.)

Ah, it makes sense, because I never asked for a refund, thanks!
