This is pretty bad.

You can have an okay time with it depending on luck, but the autocomplete method of spelling out answers will quickly tell you if your word isn't going to be there, and it doesn't interpret similar answers very well. For example, if on the TV show you said "Chimp" and the answer was "Monkey", they'd give it to you. Even the SNES version of Family Feud does a better job of that than Decades does.

Overall a clunky, joyless rendition of a game that should be a blast.
