1 hour one time trial - Free
1 Week - $7
1 Month - $15

This assumes set rates. I am in favor of tiered pricing per title or sales for older titles. The model above is meant for older games. Maybe Sony surprises and put stuff under a year old on it.

If they did a monthly service?
1 month - $30
3 month - $75
1 year - $200

Just make it subscription based, current rental prices and durations are terrible.

but they have to calculate for a profit, and 100$ a year will surely not turn any profit.

Those look like terrible prices... Possibly worse than the prices they have now... Guess im glad you arent in charge of the psnow pricing...

I think $100 for full access to PSNow titles is pretty much a steal. Think if Steam told people they could just play everything older than say 2 years for $100 a year. It doesn't make sense.

2.99 for 1 day rental
5.99 and 6.99 for 1 week rental
9.99 to 14.99 for 1 month rental
20 a month for a subscription limited to 10 games of your choice per month

anything cheaper than this is a fantasy

OP's pricing is already A LOT better than Sony's.

OP's single game pricing makes no sense
2, 5, 10, 15 hours? Wtf...
and there can't be an "unlimited" ("buy") option, that'd remove any profit from PS now.

this

that's because you keep assuming streaming costs are a "costly thing"
