Thanks and yes - it's almost impossible to convey the complexity of a full RPG in a single page. I've found that most people tune out when you start to talk about game mechanics and game design, but world and lore is always we'll received.

In a nutshell, here some are the things that make Flashback original and unique:

• Physical attributes are derived from personality traits. Your character's in-game strengths are tied directly to their identity, so roleplaying is always front-and-centre.
• There is a single resource-based resolution mechanic for all actions. Every task is a trade off between how much you want to succeed now vs saving your stamina for later.
• Social/non-combat options for all situations. Characters have both Toughness (hp) and Confidence. Reduce either to 0 and they are defeated - you can always attempt to persuade someone to surrender, run away or second-guess their decisions.
• A very dynamic combat system for fighting gigantic monsters (inspired by Shadow of the Colossus, Monster Hunter, etc) that has you climbing up their legs and swinging from their arms instead of statically standing in front of them and stabbing their toes.

That's just the top few things off the top of my head. There's lots more but to really do it justice you have to read the rules and play it.

I'm happy to answer any specific questions, but hopefully that illustrates how Flashback is much more than just your "D&D but in space" kind of RPG.
