I already feel like I do this by adding everything into Sims 2 inventory lol. Adding one room at a time makes it easier to unpack.
The boxes in game would be cute and fun. Maybe a moving truck would pull up and there could be automated movers who know how to get the boxes to the next location safely.
Really like the idea of skills influencing how well a Sim maintains their living space and puts their bookshelf back together.
