This tech tree is a compilation of 2 files created by Saamrory and includes both a Technology Tree with the short effect descriptions beneath the name. Much the descriptions had to be in shorthand because of space restrictions. For example Fac = Factory and Education short effect description only reads "Bonus to Rsrch" where Rsrch = research. If you've played the advanced rules before you should be able to figure out what the abbreviations are. If anything in the doc is wrong you can pm me and I will post a new one.
