Renting is dead. The generation of children that used to rent grew up, got jobs, and bought new. Rental stores have all but died out in my neighborhood where there were 5 last year - I can bus for an hour and a half to reach one, an hour and a half to get home, and another 3 hours there and back the next day. For 10 bucks on the rental alone, before bus tickets. (Over 5 bucks, transfer expired by the return trip.)
We live in a world where "Pre order now" is 98% of game advertising. Devs want you to pay full price for something you don't know you'll like, and then go one step further by trying to fight used game sales with bull like online passes? Game gets leaked two weeks early? Why the hell not, go for it. If you like it, buy it. If you don't, you just saved yourself from paying over 60 dollars for a piece of trash.
The fault lies completely with the devs on that one. They want your money before their product is even out - and this usually includes exclusives that shouldn't be exclusive (See: Deus Ex Human Revolution and the Grenade Launcher as a Pre Order exclusive, or example)If you don't pre-order, you lose out on a lot - but hey, all you know about this game is "Pre-Order now!" Because they're not giving you one shred of ANYTHING to tell you if the game is for you or not.
Best example: Rage. Rage came out earlier this year. Back in like March, I was being bombarded with "PRE ORDER NOW!" and "Honk to get some random dude in the game" and other stupid ads. Not once before August (At my local Gamestop) did I see a game trailer. I didn't even know what GENRE it was. Not tell me what kind of freaking moron I would have to be to pre order that game if I know nothing about it?
So if I was curious about Rage and there was no demo (I wasn't so I didn't check) you bet your ass I'd pirate it if it was leaked early so I'd still have time to get in on the pre-order bonuses.
Honestly, there are only two kinds of people who would say there's never any reason to pirate ever. Firstly, those who are rich enough to pay any tariffs on imports for games unavailable in their region. Look at all the games that never leave Japan. Want to try them? You can pirate them and see if they're worth importing, or just import them all, which carries an astronomical price tag. The other group are the trolls, plain and simple.
EDIT: And before anyone else calls me a criminal, I want to clear the air. I currently posess two pirated games: One game that I couldn't acquite in my area and is being shipped to me from another country (playing this till it gets here) and one game that I loaned my step niece that she lost, so I'm playing the pirated one until she finds it to give it back.
