The question for me is not what character is most like me. No idea. Instead, what game character would you like to be? Most game characters lead pretty repetitive, soulless, difficult or pointless lives. Who really wants to be Pacman? Sure there is the occasional high, the chase, but ultimately that pill addiction is going to get him killed.
Anyway, I reckon Big the Cat has it pretty good. Any cat who can fish has got to be happy, he certainly seems to be thriving.

I want to be Big the Cat.
