[quote="Braveheart"]How do you convert lion years into human years when taking age as a factor into RPs?

You're probably looking at a 1:4 or 1:5 ratio, somewhere in that zone.
Maturity is reached at 3 years, though lions may be put out of the pride before then as a self-sufficient sub-adult. Normal lifespan tops out around 14 years for an adult male, though I think you could make the exceptional '100 year old' analogue a 20 year old lion. A male lion is also unlikely to be 'king' ( read: displace an established male lion ) before 4-5 years which translates into 16-25 years old in human years.
