ICRPG is a fantastic step towards the future of tabletop gaming. It strips away all the "clunk" of rules heavy systems, yet keeps every action codefied in a way that is simple and direct. Effort is the mechanic used to resolve how successful or not a "success" was, and is an amazing take on variable success.
Beyond the epic core mechanics and nearly 20 pages of revolutionary GM mechanics for driving the action, ICRPG also comes with a plethora of items and loot premade and ready to go! The two world primers are excellent ways get right into the action as well. The index cards are another top highlight. Amazingly detailed artwork and easy print-n-play functionality.
This product and all it's pieces can be used modularly to enhance your existing campaigns regardless of your home system, or completely replace it! This is awesome!
