The Hammer lost 7-3 to Adrian Lewis in the 2012 final at Ally Pally but has some great memories after dispatching Dave Chisnall, Kim Huybrechts and Simon Whitlock during a memorable run.
Now the 45-year-old is fully focused on another happy outing in North London and starts his bid for glory against James Richardson, who defeated Raymond van Barneveld in the first round last year.
"It was a great performance last time and to get to that final was a great thing to happen for me in my life," he told sportinglife.com.
"It's also disappointing that I didn't win it so hopefully this year I can get to the final again and then who knows what will happen.
"The form's good at the moment and I'm playing solid so there's no reason I can't do the same as last year and go then go one step further.
"It's everybody's aim and for me because of the experience of last year I need to win the final to prove just how good I am for myself and my fans."
Hamilton took a 20-year break in his darting career after early experience of the county circuit but there are no regrets after proving his pedigree during his second spell at the oche.
"You can always say you should have done it earlier but now I've done it," he added.
"I don't think I've fulfilled my career abilities yet but I'm not far off doing it.
"We can always go back and think what I could have done when I was younger but it doesn't always happen.
"I can't look back and can only look forward so the next few years could be important to me.
"The money in the game now and the quality in the game is making people stronger.
"There are no easy games at all so I'm looking forward to the World Championship".
