FATAL & Friends: Giant Allege 1
Giant Allege is, in its own words, a "Heart-Pounding Robot Courtroom RPG" from Japan, which boasts the following key points:
It doesn't require a GM or a scenario! The rules establish everything necessary for play, and the system has no particular need for a game master.
It doesn't require roleplaying! It certainly spices things up, but it can be played like a board game.
Everything is player VS player combat! Use your giant robot and battle skills to defeat the opposing players and get your way.
It might not actually be an RPG! As all the above suggests, it exists in a strange place in between RPGs and board games.
Each of the players controls a giant robot pilot slash lawyer in post-apocalyptic Australia, fighting to claim justice for their client. The last one standing gets the verdict they desire. The rulebook is distributed as a 28-page PDF, so hopefully this won't take too many entries to get through.
Next, I'll properly kick the book off with the setting chapter!
