The idea of inheritance for new PCs is not new, but the usual idea is you can only use it once (in my life as a player? with this DM? in this campaign?) and enact a 10% tax. But when you die you're more than likely to lose all your good stuff in a TPK or down a Hellmouth.
How about this: When your more experienced players roll up a new character (no need to bog noobs down with more to think about) give them the choice of +3 hit points, or a will that grants any gear and money that is recoverable to their next PC. No tax, but you still don't get the stuff down the Hellmouth.
Choose to Use Languages
I love languages and scripts and I'm ashamed to say they aren't much a part of my game because my world is getting fleshed out as we go. I never know what languages to offer players when they make up new pcs.
How about this: Players get the same number of languages your system says they should but they hold onto them like chits to redeem later. Dead languages and scripts cost three language chits. Monsters and other races require two, human languages just one. Now, any time one of these come up in play, players can decide if they want to know this particular language. I think it could be quite fun asking players to explain how the peasant fighter came to know linear B, or the cleric the erotic language of the courtesans.
