He simply sees it as a new challenge. As if an alien species is invading earth, and it's up to him to find a solution. And not like it's a piece of trash, hacking a 20 year old game which is now played on uneven terms.
Flash is like some superhero (with superintegrity too).. i feel like I'm becoming a better human just by watching him fight with all his power against this guy.
And how does he still have that curiousity about the game after so long... Seriously feels like watching beasts like MJ, Maradona or someone similar in their prime. Only Flash is probably even a higher quality human.
