I am given the impression of a horridly obese person lying down on a skateboard and punting themselves along like a stranded fish. Shame to hear about the roombas though, that would've made a truly noble steed...
As for the expenses of basing stuff out of a zeppelin or yacht, exactly how much more does a big moving machine like that cost, in comparison to an equally large yet immobile corporate headquarters? And bombs are bombs pretty much anywhere you go, security is an issue regardless of where you hang your hat (and last I checked, it's more difficult to get somebody into a great big floating fortress than it is onto someone's doorstep. Unless you can somehow throw grenades that high up, in which case there's definitely a problem). I basically view the mobility as the major defensive bonus, as you can just keep flying or sailing about to new locations so that nobody knows exactly where you are. Just issue a message over corpchat as to where you're going to stop next so that nearby members can get ready should they need anything.
Hadn't thought about the weight restrictions, however... Wasn't really aware of them, to be honest. So there is that. And I don't even know what all you're supposed to stock a corp with.
Aren't zeppelins craft-only? I don't really know how you'd compare that to the cost of maintaining a formal HQ.
Of course, what'd be REALLY cool is a zeppelin that has all the necessary things for building gyrocopters... But I'm getting way out beyond my area of knowledge, and venturing all too far into the realm of dreams.
Just finished up my last medic job. It says you won't get any more XP for it, but do you still get paid for completing a job after you've done it however many times? I'm still trying to think of what I should do next with this character... I was thinking of bumming some help from frog to go down into the sewers and get the Swollen Brain mutation, but I'm afraid that the drop to Cool would force me into a permanent state of 1337speak. Scavenging is an option, especially now that I've gotten all those lovely boosts from the corpse grinder job, but I'm already having issues with carrying weight.
Repair would be a nice stat to get some work on, but currently the only thing that routinely needs my expert touch is the gin tub (how does that thing work, anyways? Are you ever supposed to put stuff in there?). The utility worker job is a bit wonky right now, since it refuses to have more than two items down at any one time.
Currently, those two places are 1) a power transformer in the Gold VoxGuard-ed back room of 420 High and 2) some giant frikkin' alligator's nest in the sewers. I've been trying to smash a transformer in gangland into submission, but that's not going particularly well...
On the plus side, I've found a use for all those improvised bandages I end up with after grinding craft.
