Valve will refund games past the 2h window if you have a reasonable reason. I had to the other day when I just couldn't get a game running despite following all of the community suggestions. Ended up going over the 2h window without realizing it and they approved the refund without issue.
Valve's refund policy before they made it better was probably the closest to anti-consumer you could call them. In many countries it was straight up illegal and had to get put through court before they would give you the rights you had as an australian citizen for example.
