Well that's the thing, are there going to be any Fallout/vault mechanics at all. Or really ANY game mechanics.
Because if it's nothing but the usual, talk to women until X stats > Y... then you can bone them. Rinse, repeat, grind.
It's not a Fallout game. It's the usual fuckquest with stats triggered blocking, but with a Fallout skin.
But if it was actual vault problems gameplay with good and bad concequences and different acting characters (no all just bimbos waiting to be screwed regardless of their description), I'd be eager. But not holding my breath sadly, the writing and game mechanics is usually the weakest part.
