Charles Martinet in Guinness records for most performances as a single game character
This is a couple of weeks late, but I figure more people should know:
Super Smash Bros. Ultimate is Charles Martinet 100th performance as Nintendo's mascot, Mario, and the Guinness World Records has put him in their records.
Couple of random trivia: Super Mario 64 was not Martinet's first time voicing Mario, that was the CD-ROM version of Mario Teaches Typing, which the MS_DOS version was the first time Mario was voiced (but by someone else).
