Quoted from JY64:
I keep hearing DI being called a hit I just don't see it being that neather the 150 CE or 2500 LE have sold out I would like to know what numbers are a hit a 1000 games 1500 game ?
Well, I'll speak to what I said, referring to it as a "sleeper hit".
If I look up the definition of that term, wikipedia defines it as:
"In the entertainment industry, a sleeper hit is a title (such as a book, film, song or game) that becomes successful gradually, often with little promotion."
So, by their definition, we're talking about successful. It doesn't necessarily have to light the world on fire, but was it a success for JJP? As opposed to a money loser. It also started slow out of the gate and built fans as more people played it.
I don't think all LEs and CEs have to sell out for it to be a success, and anecdotally we know it has had decent sales.
