The conflicts weren't very good. Like having to hide his level because beta testers are evil. 1. Nobody cares if you're a beta tester in reality, and 2. That's retarded. You're in a game that will kill you, why would you not want to have good players? Why would you actively get on the bad sides of good players? Most conflicts in the Sword Art Online section are instigated by him hiding his level, but it's really stupid.
And Kirito is magically the best at every game he picks up. People should catch up to him seeing as they're trapped there for years, but he just keeps being infinitely better than everyone else.
