While I liked playing it with my cousin I fail to see how is game from 1991 "the mother of all games" when I enjoyed playing plenty other games already in 80s. Also as for the games from 1991 I enjoyed Crystal Caves much more playing it in father's work.
Btw. I find Worms much more enjoyable/funnier, though it's pretty much same concept.
edit: same year was also released Lemmings, which blows graphics/UI of this out of water, SE feels like 80's, Lemmings at least 5-10 years younger, while both were released same year
