For Robert Williams, buying and selling trading game cards like Pokémon and Yu-Gi-Oh! is a lucrative business.
Competitors play these card games by strategically building their decks, with specific cards allowing players to make moves.Mr Williams said while the most popular trading cards, like Pokémon, Yu-Gi-Oh! and Magic: The Gathering, became popular in the 1990s, there were a host of other cards now coveted by collectors.
"I own a time twister; it's an old power nine card in Magic: The Gathering, so it's in nine of the most powerful cards," Mr Lodder said. "If they play a card game with somebody else, it doesn't matter what colour hair you've got, what your physique is ... it's not about sporting prowess."It's a very different type of muscle flex ... because people will spend hours upon hours developing their decks, characters and strategy.""The perception is that we're a bunch of geeks and a bunch of nerds, like we are, but people come from all walks of life," he said.
