Because the “default path” is different, a free trial would have way less conversion than the current system.
With a free trial you have to take an action to buy it. With a refund you have to take an action to be refunded.
Or they could do it like SaaS, where you’re automatically charged at the end of the trial unless you decide to cancel before… But that’s a bit convoluted and it wouldn’t bring much compared to the current system.
Personally unless it’s a dirt cheap game I do enough research before buying and I rarely have to refund. But I definitely refund if the game is not at the level of quality that I expected.
Yeah, sometimes it’s weird - for example when a king gives you a sword that has been in his family for generations, you go to the merchant and it’s not worth more than something you looted on a bandit.
