I only pirate games that I wouldn't mind playing but also hate the publisher, or the publisher makes the games annoying to play despite steams easy UI and setup.
Games from EA, Ubisoft, Rockstar, etc I will pirate with no remorse and then place the launcher link in my steam library.
I don't think ita unreasonable to do so, but it should not be in addition to the deposit. Should be one or the other.
Like, over time it's more likely for damage from pets to build up and can easily get over $250 after a year or two.
But good luck getting over $250 damage in 2-3 months.
So I would see it reasonable to charge per month per pet, in the assumption that there will be damages to fix building up over time.
