Can I play stadia without credit card or debit Card
I believe you need one for account creation, you can use the card and immediately unlink it though to prevent it from charging your account after the trial is over.
I don't have credit card
I have with paypal
It asks for credit card
Doesn't paypal need to be connected to a bank account? Just use your debit card... if it has a visa/mc logo... it count's as a credit card.
that depends heavely on the country your are living in.
For example, I live in Germany. I was able to buy the Bundle using Paypal but I've to buy each game via my credit card - not option for Paypal is there available.
There is no thing to do
