Two things always bugged me about Give or Keep: you weren’t actually “giving away” anything, and the “keep more than you give away” mechanic rewarded greed.
I mean, I guess. I just assumed that you were "giving away" the prize you didn't keep back to the house. I suppose it can be viewed as rewarding greed, but I never watch the game thinking "which one of these prizes would I want the most?" I'm just answering Bob's question of "which one of these is more expensive?" It's a quiz to me, not an exercise in personal value.
I love the concept of the game, I'm sad that it didn't play out well enough on TV for them to continue playing it. I'd love to see it come back with honestly no changes except bringing out and displaying the small prizes on stage instead of having to do the Shaky Turntable Shuffle.
Though I do love the idea of the prizes not kept being given to someone at home.
