First off: VERY few changes in 7th edition. DON'T GET SCARED OFF BY THOSE WHO SAY OTHERWISE. Your old books are STILL PLAYABLE.
These quickstart rules are great. You can play the game for a long time using justr these rules, IF you have a list of occupations because these rules list just a few. So if ypou're on a budget, this plus an oldf copy of the Investigator's Handbook from a previous edition would let you play for yonks. Chargen is simplified, so when switching to the full game, players might want to redo their characters using the full system. As far as I can tell, all of combat and sanity rules are here and they offer all the complexity I need.
