Nice spreadsheet.
I am a bit of an Excel Geek and have recently created a spreadsheet to help me track some of the things I am OCD about. It can automatically refresh a tab with revised collection data from BoardGameGeek and links to another tab with my augmented data.
705: Total collection size including all owned entries in BGG Database
-003: Remove entries for miscellaneous accessories
-002: Remove entries for books
-044: Remove entries for items I am trading away
-243: Remove expansions
413: Number of games that I own and want to keep
-005: Remove entries for standard playing card games
-003: Remove entries for standard dice games
-002: Remove entries for dominoes games
-012: Remove entries for Decktet games
-075: Remove entries for Icehouse games
316:Number of games that I own that are not part of a rules system
-004: Remove entries for Print & Play games
-001: Remove entries for Print & Proxy & Play games
311: Actual number of commercial games I own
I am building a collection utilization tab to track plays / collection. I am also looking to log plays and win stats to award goofy little prizes to our game group members. I know...
...I am VERY OCD.
