The Cortex Plus System is a toolkit RPG system that evolved from Margaret Weis Productions, Ltd's Cortex System. It has been used for three published games and one published preview to date, and the design principles are in the Cortex Plus Hackers Guide, a book of advice in how to create new games using Cortex Plus, and list of new games produced via kickstarter.〔(Cortex Plus Hackers Guide Kickstarter )〕 According to the Hackers' Guide there are three basic 'flavours' of Cortex Plus; Action, Drama, and Heroic. Of the three currently published games under this system (with a fourth announced), Leverage: The Roleplaying Game was nominated for the 2011 Origins Award for best Role Playing Game,〔(Leverage RPG on RPG Geek )〕 and Marvel Heroic Roleplaying won the 2013 award and the award for best support as well as the 2012 ENnie Award for Best Rules and runner up for Best Game.〔(Marvel Heroic Roleplaying on RPG Geek )〕 Note that despite the similarity in name, ''Cortex Plus'' is not the Cortex System, also produced by Margaret Weis Productions. ==System== Unlike the Cortex System, Cortex Plus is a roll and keep system in which you roll one die from each category and keep the two highest dice in your dice pool. What goes into your dice pool is whatever is considered important for the game you are playing - but different stories have different things they consider important so the implementation of the system has been different for each game so far. All versions of Cortex Plus use standard polyhedral dice and the normal dice notation ranging from d4 (a 4 sided tetrahedral die) to d12 (a 12-sided dodecahedral die), and narratively notable features are given dice from this list, with d6 being the default. In all cases Cortex Plus uses dice pools ranging from d4 (terrible) to d12 (the best possible), and every die in your pool that rolls a natural 1 (called an 'Opportunity') doesn't count toward your total and causes some form of negative consequence which, depending on the game, either creates a complication for the characters to overcome or adds to the Doom Pool that provides the Game Master resources within the scene. Adding a d4 to your dice pool is considered a penalty because it isn't likely to roll one of your best two die results and there's such a high chance of rolling a 1. Most versions of Cortex Plus (other than Smallville) give the character a set of three distinctions that they can choose to add to their dice pool either as a d8 to assist them, or as a d4 to hinder them - but they gain a plot point by using the d4 option. Equipment is normally handled by enabling the character to do things (you can't shoot someone without a gun) but where it is especially notable it is given a dice rating and added to the dice pool as an asset. And things that get in the way are treated similarly, and added to the dice pool as complications. Cortex Plus also uses Plot Points - the normal uses of which are to establish something as notable (turning it into an asset), power a stunt or ability, to add a die to your roll, or to keep an additional die after you have rolled. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cortex Plus」の詳細全文を読む スポンサード リンク
