I was cautiously thinking about one day perhaps strongly considering purchasing a PS4. This thread is not encouraging.
To be honest, I'd rather sink my money into a nice custom PC with a top-end nVidia graphics card. You'll probably spend a bit more than you would a game console, but you'd also have a platform which could emulate others'.
The only concern is not being able to get certain games that are made specifically for those platforms --but I'm sure with enough pressure to move them to others, it would be worth the wait.
I'd really like to see "The Last of Us" on PC, and heck, hopefully here on GOG some day, but until then, I have more games than I could ever play in my lifetime.
BTW, controversial as it may be, Saint's Row 3 is a fun sandbox game. I enjoyed it.
