dX Armored Core Mecha Mercenaries
I'll be honest, I never finished a single one of the video games, but I remember being impressed by the mercenary Ravens and the missions you'd take on. So knowledge of the series is not necessary. The game is just inspired by, not based on, the video game series.
This game would have you both building and piloting a giant robot on mercenary missions. You'd earn money and build points to improve your AC (the robot) after completing missions. Sometimes you might find a cutting edge piece of equipment from rival Ravens (the pilots) that you can install on your own AC. Other times you may find your equipment gets damaged and needs critical parts to repair.
The game would have some down time for team planning and pilot training, where the players could also upgrade their AC or train their own piloting skills.
The missions would be envoy escorts, envoy interceptions, base protection and base infiltration.
Some personal drama may occur for the PCs, like romance or political leverage, but those would be minor focuses at most.
As a closing note, I realize dX may not be the best system for this. I just don't feel like learning a new system to GM it. I want something simple, even if it's not the most elegant system.
Thoughts?
