If you’ve got the room, I recommend mixing it up. I used to have just pins and all that would happen when kids came over was them starting games, launching a ball and walking away.
About three years ago I got a Big Buck Hunter HD, a couple multicades, a Photo Booth, two, linked Artic Thunders, an Ice Cold Beer and I just got an Ultimate Big Punch (which everyone loves). Plus, I still have managed to cram a dozen pins in there. Now, there’s something for everyone!
