>>96026248 (OP)Did it a few time in Traveller campaigns. I ran the characters through their careers - they played out an adventure, did a 4 year term in their chosen service to gain skills, repeating as their characters went through their entire working careers. When the characters became to feeble to be effective (aging dms pile up in Traveller past 40), they rolled up a new character and they replaced the old with the new 18 year old, gaining the earlier character's stuff as their inheritance. I had a bunch of players in a Merchant game go through three generations like this, the first lot starting by flying a rust bucket Trader, the kids getting the payed off and upgraded ship, with their kids finally (after many adventures against competitors, pirates, sirviving a war, etc) inheriting a small successful shipping line. Keeping the bloodline going and building their empire gave them something more to aim for than the usual 'loot and kill everything' in other games. Looking for potential partners (with associated enemies and allies in their families), as well as looking after them once married also presented a lot of good roleplaying opportunities, adventure hooks and backup characters for them to play.
