I was quite disappointed with TNPiR '94. I thought it would be more like the Kennedy version (which I loved, and still do) and when it wasn't, that was pretty much it. I tried to watch it and enjoy it, but I couldn't.
Scattergories was another one I thought I would enjoy (a good game with celebrities), instead, it just put me to sleep (literally).
Lastly, MG '98. I've been a MG fan my whole life but the lack of 6 celebrities, no wheel (I do enjoy the Star Wheel episodes much more), and low-cash payouts killed it for me.
