I'll send a PM to Wykyd soon then, ask about things abit and all, reading the materials I think the Gunner is already pretty well made though so not sure if I should edit things, rather adopt the character as is and play it. Though I am usually more for creating my own but a role is a role and can be interesting afterall to explore outside the usual sometimes.
Anyway, it looks like an interesting game and would gladly try and join along in the gunner's role if its an option.
As for the thought of side-characters or undefined roles, I might consider that as well but didn't want to intrude on the game with such thoughts when it seemed it had already gotten on the move before with a nice gathering, but as an opening came up I naturally wanted to voice my interest.
Thought to think on it, a few thoughts do come up though not sure how long lasting those would be... or how useful...
-EVA specialist: Something broken on the outside, or the crew needs to take on something out there but who's stupid enough to jump out of the ship in a suit, and risk it whether or not they land on target and can get in before being spotted? Extra-Vehicular Activity Specialist is your best bet, the guy may be crazy and love the risks but your threat to blow the merchant marine's ship apart from beyond weapon range becomes a lot more convincing when your EVA specialist previously thrown out with sufficient velocity (and means of reducing that velocity before impact) at right angle can give the target a treatment they'd rather not have.. or makes certain the ship's damaged exterior gets tended to while the mechanic handles what repairs are necessary indoors.
-Information Systems Tech: Probably a bit of a weird guy, 'Comms Officer' and using Sensors, an IST is a spaceship's annoying little guy, tending to listening to the signals trying to pick up something useful, occasionally trying to hide or mask the ship's own signature, and ascertain that whatever mark the pirates might take up is what it seems to be, as far as systems can tell... and possibly involving the enemy ship in some electronic warfare if such is an option in ship-to-ship encounters, if not, more likely to spend time trying to assist a pilot or gunner making sure the systems are workign top-notch, possibly a pain in the ass for the engineer by riding the systems so hard in the heat of moments the Engineer has to chase him with a wrench held as a club to get him to just say 'sorry!'.
Beyond those, the thoughts wander to the more alien species, but figure shouldn't involve them too much, already on shaky ground on the whole acceptance so waiting around to hear.
