At lunch today (I was a guest), another guest showed me the "latest game" that she had bought: Snatch. I hadn't heard of it, which surprised everyone.
When I saw it, it was immediately obvious that it was Anagrams. It simply had redesigned letter tiles and a white cardboard tube.
It's curious how many games are simply a repackaging of other games without even acknowledging their origins. Not even including *-opoly's and games intended to bypass copyrights and trademarks.
An infamous case is Alien Encounter, which, for all it's fancy space-themed board and tokens, is simply the game of Go on a 9x9 board.
