This was the reaction from Spanish casters to G2 Esports’ final game against RNG.

But all the excitement isn’t for the Grand Finals of Worlds 2018 -- it’s just for the Quarterfinals. There are still many days to go before a team can be crowned champions.

So why are these two wins so significant and so emotional?

Because this top four team lineup marks a new historic moment in League of Legends.

This is the first time a North American team has reached the Semifinals of the World Championship.

This is the first time that there won’t be a South Korean team at the Finals since 2012.

G2’s 3-2 victory over RNG is one of the most stunning and unexpected upsets in League of Legends history.

Both the NA LCS and the EU LCS have long been seen as the weaker regions compared to China and South Korea.

The Western teams would go to South Korea for bootcamp to hone their skills and prepare for major competitions. North America in particular had the reputation as the region who would sign brilliant, skilled individual stars onto their rosters, but then fail to perform well in international tournaments.

It seemed like the LCS teams would often have to find talent from the other regions in order to win.

But over the weekend, both G2 and Cloud9 showed that they can win on the international stage with their homegrown players, some of whom are untested rookies, and beat out the Chinese and South Korean giants.

For NA fans in particular, this is the first time they’re able to root for their own region.

This was the ultimate underdog victory

Both Cloud9 and G2 Esports were the third seed of their regions going into Worlds.

They were seen as the worst teams out of the Western ones at Worlds.

But the gauntlet run, the Play-Ins, and then the Groups Stage brought out a better, more confident level of play in both teams.

But G2 outplayed the world champions, punishing them for depending too much on Uzi, punishing them for ignoring the fog of war, and punishing them through skillful use of game mechanics.

While some cautiously thought Cloud9 should be able to match South Korean team Afreeca Freecs in skill and teamfighting, history still gave many NA fans pause. No North American team has ever beaten a Korean team in a best-of-five at Worlds.

But now Cloud9 has set a record.

Invictus Gaming is the last Chinese team left in Worlds 2018. They will be facing off against G2 on Saturday, October 27. Cloud9 will be playing against Fnatic on Sunday, October 28.
