Ghostbusters is just a heck of a fun game design. The 1st edition is marginally better than the 2nd (not uncommon as these things go), but the general concepts of the game are wonderful. The ideas in this system - dice pools, define your own skills, single pool of resources - have had an outsized impact on game design over the years. Plus, it's a fun, light, simple design which deserves to be played.
To be clear, the authors on this were Sandy Petersen, Lynn Willis, Greg Stafford for the first edition and Aaron Alston & Doug Kauffman on the second.
