Re: Blast Off
Blast-Off was not that complicated, as I recall, but it suffered from a frequent problem: almost zero interaction between the players. If it wasn't your turn, you did nothing.
Apart from occasionally knocking people off the moon, there was very little you could "do" to anyone else.
Many boardgames have nostalgia value without much play value.
Even the magnificently bit equipped "Railroader" had this. Even the dynamite placing was almost automatic: whoever it would hurt most, unless a personal vendetta was in operation.
