Call of Cthulhu is and has always been a fantastic RPG. The newest 7th edition is a nearly perfect RPG. I could not give this 5 stars for two reasons. There are two updates to the rules that I absolutely abhor and I wish they had not done in 7e.
Bonus/Penalty Dice: This is clearly a D&D5e ripoff of the advantage/disadvantage system. Chaosium's implementation is overly convoluted. "Roll percentile dice then reroll only the 10's die, choosing higher/lower 10's". Ridiculous. Why not just reroll the percentile dice? Or, better yet, lets not even use this dumb rule at all. If an investigator deserves an advantage or disadvantage merely award a +/- 10% to the roll. I absolutely hate the Bonus/Penalty dice mechanic. It takes an otherwise a great game system and makes it clunky. I wish at the very least that this had been made an OPTIONAL rule.
Stats changed to percentiles: Whats wrong with a STR score of 3 to 18? After 6 editions why change it be 01 to 100? This seems like an arbitrary change made to create the illusion of an "overhaul" of a system that worked great before. This change was completely unnecessary.
Other than those two things, its a fantastic game. Heres to hoping they fix those garbage changes in the 8th edition.
