BEST THING EVAH!

I'm quite surprised, but pleasantly so. I only have two problems with this:
2 hours can be quite a short time; what if a game is only three hours (and the developer implied it was longer) but you hit the two hour limit? What's to keep a developer from releasing a game and only polishing the first couple of hours of content? I suppose this is perhaps over-thinking it, but, you know, could happen?
Cards: Do you lose them? What if you sell cards? Are you going to delay card drops by two hours? If you get card drops, are you blocked from refunding, and if you refund a game with card drops, do the drops reset?

There are not many games that I cannot beat within 14 days, me thinks....

EDIT: hadn't read the steam page about it before commenting, stupid me.....

Awesome now I can finally buy games from pre 2005 & test if they work. Valve should let cards drop after 2 hours of game time.

I have to assume that this is, at least in part, due to the efforts of laws in Europe regarding a 14-day requirement for refunds.
So...

Thank you, Europe! :)

inb4 New Policy: Cards will not drop until the 2-hour mark has been reached.

nothing really new for eu citizens since this was already valid years ago ;)

if i understand correctly:

1. buy game on friends PC
2. download game on home PC
3. return game next day on friends PC
4. play offline on home PC as long as u want
5. profit

a question:

I want to buy now Pillars of Eternity with -33%

can I ask I refund if the price will be lower in the last day of sales, but I played more than 2 hours?

thanks

EA been offering a 30 day money back refund for any reason for years it was about time steam did it too.
