I've created a set of tables to be used with dice for randomly choosing investigators in Tibs' Introductory Scenarios for Arkham Horror and its expansions.
The set of tables (with instructions) can be found here: http://boardgamegeek.com/filepage/91655/investigator-selection-tables-for-tibs-introductor
Tibs' scenarios (a fantastic way to get introduced to Arkham Horror and its expansions) can be found here: http://boardgamegeek.com/filepage/69008/introductory-and-expansion-scenarios
Any comments, critiques, and/or suggestions would be welcome.
