Pacifism
Leonel grinned as the Go board disappeared. It seemed that Old Bastian had a bit of a temper, though that much should have been obvious after their first interaction.
Truthfully, he was a little embarrassed. The reality was that he planned on giving Leonel a chance even if he lost. That was because he couldn't even remember the last time he lost in a game of Portal. Winning or losing didn't necessarily mean that Leonel was inferior to him, he was just making things a bit difficult on Leonel on purpose.
The reason for this was because the most important aspect of the game, the portals themselves, were meant to be created at random. The issue was that there was no one skilled enough to make them. The game was extraordinarily complex.
