I concur with Yue and would like to point out that Freelancer has always appealed to me specifically because its scenario and setting distance themselves from the stereotypical futuristic game. (Vanilla) Sirius only features one brand of alien, and a brand that's far more subtly implemented than in other sci-fi universes; there's a refreshing lack of pseudo-magical powers, barbarous alien hordes, hideous mutants, supersoldiers, Death Stars, and betentacled Lovecraftian monsters from the farthest reaches of space. Self-aware or killer robots are another hallmark of generic sci-fi settings I find enjoyably absent in Freelancer; any and all robots that existed in the vanilla game were menial drones that performed vendorlike functions. They evidently weren't considered even remotely sentient or self-aware, as Research Station Baxter's robot population was left behind when the base was abandoned by its human custodians. Gammu was a developer joke and an Easter egg, nothing more.
Seriously, shy away from the robot lolwuttery, please. Not only does it entail only minimalist roleplay, like Yue says, but it also leads to Freelancer becoming increasingly unoriginal and dull.
EDIT: Just realized you're the man behind Mon'Star. I apply much the same criticism to your terrorist, by the way. Don't mean to offend at all, just stating my viewpoint.
