The aging "system"

[Agrajag]

Will we really get to see the aging system in action?
Because if even long games take 10 years... What unit can you recruit that won't last 10 years?
Even the oldest of soldiers won't be over 40 (and 50 is far from death).
Besides a cooler BoT, the only effect I can imagine is mages aging (and even then, I'd expect mages to have very long lifespans, and not to be recruited a few years before dying of old age...)

So enlighten me, you have the game, does the aging system play a role in it, or is it irelevant? And will it be tweaked if it is found to be too minor or too major?
