As far as I know, yes, Brock is the first major figure to be in 3 major sports gaming titles, unless you'd like to count Shaq in various NBA games, UFC Undisputed 2010, and Ready 2 Rumble Boxing. I stopped liking Cena shortly after his feud with RVD and the new ECW in 2006. While I loved Cena as a heel and continued to like him as a face, I grew weary of him by the time I started to see through his gimmick. It was the same crap every week, which The Rock was guilty of from 2000-2002. The difference is, Rock still found ways to keep me entertained when he would do or say something different. Conversely, I had started to fall asleep during John Cena main events and his promos started to get more and more bland. If there was any single fault of Cena, it was that he allowed himself to be booked as Super Cena. While I know that there are those who'd say we'd do the same thing in his shoes, if Cena really loves his craft, he'd care about his character evolving. Look at the many iterations of Chris Jericho and even HHH. Heck, The Rock went from varying degrees of the same cocky heel, even as a face. Hollywood Rock in 2003 was one of the best heel gimmicks I've seen in recent memory, and it was nothing more than a retread of classic '70s arrogant heels like Nick Bockwinkel, but with a real-life Hollywood flair.
