I think traditional Lego died when they introduced the parts separator tool - back in my day, you destroyed your fingernails (and sometimes even used your teeth) separating parts. Attaching two 2x1 thin bricks was considered horrific, because you knew you'd never be able to separate them anymore. Kids these days have it too easy.
