Alignment I don't care about. I'd like to see something lie the Personality, Bonds, Flaws, and Ideals related to Backgrounds, maybe something like the personality tags Solasta uses or the reputations Pillars of Eternity uses. But I can't help seeing alignment as increasingly insufficient as I get older.
Meh to each there own, just something I'm used to in d&d games, thought it was done pretty well in Pathfinder: kingmaker the little bit I did play of that game.
Ya, tags would be cool, I did like the Solasta Tag system, and would like to choose something else besides Baldur's gate as my home town/city.
Flaws would be a interesting feature, something that gave bonuses and negatives. Starting to remember fallout new vegas now : / but I'm pretty sure there was optional material in d&d at least in 3.5 don't know about other editions.
