Things from the Flood may be the best roleplaying game I have ever owned or run. Its mechanic is simple, compelling and focussed on things that drive players to roleplay. I have found it a joy to GM, it allows you to focus on the narrative over dice rolling. Its also a game that is perfect for these times, a sense of hope lost pervades most of what we do right now, whether its the failure of governments or the people we are in truly troubled times.
Mechanically the Game requires the players to own the rolling of dice, GMs set difficulty targets which are measured through a number of successes required to complete the task. The year zero engine system (Free Leagues go to mechanic) plays out extremely well here (6's on the dice are successes, the players have a dice pool comprised of Stat, Skill and any other bonus they can scrounge up). Failures can reuslt in conditions, which firstly reduce the dice pool for a player going forward and if enough are accumulated can result in the player being broken.
The rulebook contains a well documented campaign, character creation and GM sections as well as a alt history take that builds on the original Tales from the Loop and extends it. Overall its a joy to own and run.
A couple of inspirations to draw upon, the recent Tales from the Loop TV Show on Prime is actually more aligned with Things from the FLood that the original Loop Game. In addtion the later Stranger Things Seasons are a clear source of inspiration. This is a game that at its heart is a realisation of all the teen troupes, carry those awkward memeories into the Game and you'll have endless inspiration.
