The two young gamers had helped their team, Rigel, to victory in The Legends Circuit (TLC) Winter Singapore, a competition for the multiplayer online game League of Legends.
The win in the competition held in December last year meant Rigel would represent Singapore in the Garena Premier League (GPL) Spring 2016, a competition for teams in South-east Asia.
But despite being key members of the team, Kenneth Goh, 15, and Timothy Lim, 16, could not compete in the GPL held in Kuala Lumpur last month due to their age.
The competition, where six top teams across South-east Asia played against each other, has a minimum age criteria of 17.
Kenneth, who was said to be the 'best player at the foot of this circuit's league' and Timothy, who makes outstanding plays, had to be replaced by members from a rival team from Singapore.
They were upset that they could not participate with their other three team mates, after fighting so hard for a spot in the GPL.
Kenneth said: "I felt really depressed, because I wasn't able to show how good I am on stage. I cried in my room.
"Because I'm still very young, there was no choice, I have to let other people replace me."
The GPL is a stepping stone to teams wanting to compete in international competitions, with the pinnacle being the World Championships.
Rigel, without their two teenage players, finished fifth at the GPL held in KL. Both youngsters felt the team could have done better if they had been in the team.
Competing against veteran players who had more experience in TLC, Rigel was not expecting to win.
Rigel's leader, Poongundran Ranganathan, said: "Their absence definitely affected the team's performance in GPL and it was difficult playing with two new players."
He also mentioned that even after months of training with the two new members, their playing styles were still different and affected how they communicated with each other during the game.
Even though the two teens lost the opportunity to bring Rigel and Singapore to victory, they knew that they are still young and have many opportunities in the future to continue playing competitively in this scene.
Timothy revealed that he looked up to Martin Lew, who replaced him as a marksman for Rigel, and tried to make good use of this situation.
"Sometimes it's good to take a break and watch the games from another perspective," said Timothy.
However, both Kenneth and Timothy will be back with Rigel at the Singapore TLC Summer 2016 on May 29.
Timothy, who would be turning 17 next year, is particularly looking forward to help Rigel qualify for next year's GPL as he would be able to take part then. But Kenneth would have to wait another year before he can represent Rigel at the GPL.
Rigel, initially known as Corvus, was formed early last year and won several competitions in Singapore such as the Garena Novice Cup and Sitex 2015.
