Including title, platform, year of release. I am putting metacritic scores up for each game as well. If I could not locate a score for original I uploaded closest I could find and notated the latest re release platform and year. If there simply wasn't a score to put, I put "They don't have one". That only happened for maybe 10 out of 50...so not too bad.
