I don't think Ezio would be a good fit because all the Assassin Creed's were on multiple systems to me the deserving ones are those that had at least 1 exclusive game/debuted on the Playstation, or had an impact on Playstation's success. One of the only reason's Big Daddy got in is the same why Snake was in Brawl, a deal was made.
Completely agreed with. The ones that come to mind immediately are:
These are the 5 characters that immediately come to mind when talking about the PS1 era. They were the superstars of the PS1 era on top of being some of the most famous and iconic video game characters there are. Their respective series, Crash Bandicoot, Spyro the Dragon, Tomb Raider, MGS and FF helped lift the PS brand when it was just starting out. Without a doubt they deserve a place in this game over almost everyone else.
