A very large portion of my PS3 games are digital. However, the most I've paid for any digital game (not including DLC) has been 30 dollars. Only about four games have cost me 30 dollar. Not a single one of the more than that.
Anywhere between 99 cents and 10 dollars is almost every other game.
I will not spend 60 bucks on any digital game, ever.
But, you have to consider, you're getting the game a month early, and if that's worth it. Otherwise, spend 60 dollars, and have the game not tied to your PSN account and not have it take up HDD space.
Each has their positive and negatives. At 60 bucks, though, I'd stay physical.
Everyone talks about 15-20%, I'm looking for 50%+ to even consider it. Got Dead or Alive 5: Ultimate for about 14 dollars and some change. Bought some DLC to go along with it, and the price went up to 54 dollars. Must have saved at least 40 dollars on all that. Paying full price for DoA is asking to be ripped-off.
GTAV, like I said, 50% off when I bought it. Tomb Raider was 10 bucks, Max Payne 3 was 5, Assassin's Creed 3: Ultimate Edtion, was about 25 if memory serves. Soul Calibur V was even 10 dollars. But, you know what? Soul Calibur V was a game I skipped in favor of another. And, I'm so glad I did skip it, because Soul Calibur V is the worst game in the series. It might be better than Soul Edge, but that's only considering the fact that Soul Edge is so old. Which isn't really fair.
But, had I bought that game at 60, I would have been disappointed. It's a bad game. I still feel ripped, eventhough it only cost me 10 dollars.
