As a newbie, I'm really not qualified to speak, but I will say... I was like you in that I really liked playing with the fire in the old fireplaces, feeding them, watching them, listening to them. It was like TV for me, mesmerizing. I liked the heat, it seemed like a good hobby. Loved just sitting in front of the fire. I thought I would miss the crackle if we went to stoves, but we made the leap to stoves for all the good reasons that people list here.
With the 2 wood stoves we got, I'm finding that I am still enjoying the view of the flames (getting big windows on the stoves was top of our list), I can hear the crackle a little, but mostly, I am enjoying the fires even more because of the far higher heat output, with less wood. And the stoves are now getting crowded at the hearth, the kids naturally are hanging out in front of them, and even asking for the fires to be lit, when they never did before.
Like others have said, the dealer said we could get a screen to make it a fireplace again, if we wanted to, but he discouraged us from getting it, saying you'll basically never use it. (Have to respect him, he dissuaded us from some other options, and he was right about them all.) Wouldn't consider it at all now.
