Some Dragon Ball Z games (the ones I've played are Finale, Phoenix, and itty-bits of other ones) had a nice aging system. You could die of old age, yeah, but it worked because it was a sandbox system with an afterlife, and ways you could increase your lifespan. Since SL2 is nowhere near a sandbox RP game (look at all the NPC-controlled governments), I don't think having time being more solidified would be a good option. It should stay vague.
