If your usage has exceeded expenses, they could mark it 95% off and it wouldn't matter.
I have 500 hours. I paid $52 or $53, shipped with sales tax. Compare this to other multimedia entertainment products such as a film or music album with 45 minutes to 3 hours of initial content at a price between $10 & $20.
If you rushed through the game at 20 hours and didn't play again with a full purchase price, your usage will have exceeded expenses.
Considering my usage to expenses, if anything, I owe them money. This allows for the purchase of applicable merchandise without actually being an additional expense up to the general ratio.
This doesn't include whether you received additional & alternative value from the product beyond intended purpose which then compounds upon general usage with a modified ratio.
You see, when you apply logic to a concept, you no longer allow yourself to be disgruntled, in fact, you might even find your smile.
With my expenditure, I am incapable of negative criticism. Any disappointment is unnecessary and a mental health issue. The only thing I can do at this point is gossip & suggest. But any form of negative emotion or thought beyond the expense is irrational.
