Before I buy(or not) this game: how much time did it take to finish it?

i just read the reviews here:

CRamen said it will take up to 4 hours.

At least if you try to find everything, I would say more than 6 hours. I'm not finished yet, but still looking for the last two cards ...

I'm about to finish the game, but I'm still glad I bought it. It does advertise itself as a short game, but I plan on playing it again periodically as it does a great job eliciting feelings of nostalgia for so many different fantasy games I've played. I really like this game.
