OVERALL RANK

# PIECES

# SETS

# COLORS

Ranking based on buying one copy of every LEGO set, counting the number of sets containing each part, then sorting by part and color.

Overall Rank is a weighted score combining the number of parts, sets, and colors produced.

Current ranking based on sets released between 2021-2025. (2026 not included because too few sets have been released and inventoried at this time.)
