Pre-mades makeover

None, please. I agree that it's a waste of resources. Ten years later? We can all remake them ourselves if we want, many of us have, many people are already long used to the old models and changing them isn't going to make players play with them. There's just no point.

Now, if devs really wanted to fix something to pay homage to previous games, I would suggest some of the gameplay. Proper lifetime Aspirations, Sim choices and consequences that matter, more balanced and interesting Traits, and detailed, unbiased simulation that's not skewed in favor of "optimism" so that players can play out real stories full of challenges and obstacles that are relatable to life. :)
