yeah, i aimed for as many normal achivements as i could on my first run, then grabbed the stragglers via the archives, such as the one where i can't allow the broodmother to gather a single egg. The fact that the game allowed me to have double drones and swarmlings when i played from the archives only made this task easier.

Right now i'm only aiming for getting kerrigan to level 70, meaning i need to ensure i don't miss a single optional mission. hard-difficulty achivements can be done later.
