I love playing the normal life span as I like the rapid changes, having to achieve so much in so little time, and the continuation of a family. However, saying that, I'm playing my WA game/story on the epic life span (can't remember exactly what it's called, memory like a sieve, anyhow, the longest life span), as I created a sim specifically for the tomb raiding and that is going to take a while as I want to explore every tomb, do every adventure, and complete all relic collections, including the minor relic collections (i'm a bit ocd like that!). However she is also having children and once I've completed WA and move onto the children I'll be turning the lifespan back to normal.
