"But Judge Young did" This sentence pops out of nowhere and needs a little more setup to indicate that Young's primary ruling was that the copyright claim was generally invalid
Also, don't start sentences with conjunctions
" No comma after "protection to Atari"
Lowercase "defendants"
"he compared it" → "Young compared it"
"twenty-two instances" → "22 instances" per
MOS:NUMERAL
"as well as the rocks always splitting" → "and that the rocks always split"
"In the Judge Young's analysis"
"to the overall idea"
Effects
"Early in the development of video game law, it was part of the "Atari trilogy" of cases" → "Atari v. Amusement World was part of the "Atari trilogy" of cases the helped define early video game law"
The other cases should be italicized as court cases
"scenes-a-faire" should also be italicized and should have the accents/diacritics
Both Vanderbilt Law Review and University of Pennsylvania Law Review should be italicized as the names of publications
Legacy
"notes that this was" → "notes that Atari v. Amusement World was"
Once again, all court cases should be italicized
"Corp. that gave" → "Corp., which gave"
