Bloodthirsty could be a thing, how many points do you think it should cost cause this could really effect balance.
Not really sure what you mean by remove the limits while maintaining the limits. Do you mean maintaining the single pool limits of stat points? You can already increase the number of points you can put into traits beyond 12, as well as increase the number as starting trait and skill points.
Not sure arcade machines would be that popular if they only had those basic games on them, pre-cataclysm whose going to pay to play those games? Also the lack of power to the machines would make it hard to play on.
Does raise a question, how do vending machines/ATM machines work with no power, do they have their own internal battery backup?
