According to 343, their primary goal when creating Halo 4's Achievements was to reward milestones and increase replay value while balancing both the difficulty and the breadth of game modes. Their second goal was to continue with Halo's tradition of making up "weird ass" names for some of the Achievements.
Fortunately, it seems like 343 Industries refrained from focusing too much on Halo 4's multiplayer when it comes to Achievements. I honestly hate it when this happens as some matches consist of nothing but countless people doing the same thing over and over just to get that Achievement sound and score to unlock.
Are you happy with Halo 4's Achievements or am I wrong and they should focus more on multiplayer when it comes to "Cheevos?"
