Not to be an ingrate, but I am... I'll explain.
I've been a Playstation Plus subscriber since the release of the PS4. I have enjoyed the fact that as a PS+ subscriber, I get so many free titles per month on my PS4, PS3, and Vita consoles; it's really a great value.
The ungrateful side of me is screaming, "why so many indie titles?!?" Sure, they've received rave reviews, and are in fact good titles. I just sometimes can't bring myself to play an 16-bit game on my PS4 - it's sacrilege! I have about 15-20 PS+ freebies so far, that I will probably never touch.
This past week, PSN had an "Indie Flash Sale" which offered some stunningly low prices ($4-$6 for games that were $20-$30.) I looked and clicked add to cart on a lot of these, because hey - they were "just $4!" In the end, I removed everything in my cart, because I had the overwhelming fear that next month one of the indie games that I just purchased will inevitably be a PS+ freebie.
Indie developers out there should see this as a cautionary tale. Sony is diluting the market with so many free indie games, your only hope is that Sony buys your game as next month's giveaway, because the masses of PS+ subscribers are going to be waiting in the sidelines until the day it goes free.
