You rather missed my point. My point wasn't that OL's raingun's aren't effective, it was that they are seemingly the ONLY thing that he has that's effective. Now a few things also come into this. Because yes, even though they use a larger variety of constructs, it generally boils down to 'Make green thing and hit them with it.' Also, it can be pointed out that Paul is by no means a master power ring user. I'm not sure how we would rank them, but he's only got about a year's worth of training.
I just find it funny, in a slightly annoying way, that Paul has a power ring, yet his often most useful attack could be replaced by...well a gun. But maybe that's the point? Transportation and regeneration seem to be the main gimmicks of his ring.
A few things: his railguns are effective so frequently mainly because he uses them in just about every engagement, and he puts lots of effort into the railgun rounds. Crumblers are very effective against energy shields and most conventionally durable opponents, mageslayers work against magic, and angel feather rounds against the demonic. If he was regularly scoring kills solely with iron rounds, I would agree with you. But he has specialized ammunition that he chooses to fire out of a railgun but could be delivered in a number of ways.
Second, other forms of attack work plenty fine. He used gamma beams against Clayface, more mundane constructs against the invasion of Shiruta, gravity converters against the Sheeda Huntsman, destructive pulses and assimilation against the Star Conquerers, all to greater effect than railguns. But he doesn't usually open with these because railguns work most of the time, and the other weapons are power hogs comparatively. Or they're too destructive to use without sufficient justification.
"But how do they… Exchange data?"
"Emulation software. And talking."
"But if they've got emulation software anyway, surely that means that there's no real security benefit to having non-interacting operating systems?"
She hesitates for a moment. "There are… Procedures. I don't intend to give away the particulars-"
"Of course."
"-but a combination of hardware and software controls makes it substantially harder. How do your people do it?"
Ehh, this is inefficient for not just the stated reasons. They don't all need to use the same operating systems and file structures. All they really need is a commonly agreed upon communication standard and file formats that they can all convert to and from. A German speaker and a French speaker can both communicate even when they don't understand their counterpart's language provided they both can agree to communicate in English.
"Why are you sure intelligence is an advantage?"
… "Optimism?"
"Hah!" From the slight opening of her mouth, I think that she's genuinely amused. "Look at my people. We were never as clever as the Psions, but when we first rose to the stars the only other competition were the Branx. We felt ourselves their superior."
Intelligence is absolutely an advantage, but it has diminishing returns if you can't fix other aspects of your species as well. Internal unity is helpful, as is the ability to peacefully coexist with other races. Otherwise
they nuke you back into the Stone age.
I guess the Maltusians need internal unity less because even a group of a dozen of them is an incredibly powerful force. But if they actively fought each other over agreeing to separate peacefully, then they likely wouldn't be more than a violent blip in the history books.
The other guy's argument that being intelligent means nothing if you nuke yourselves into the stone age is fallacious; if you nuke yourselves into the stone age, chances are your species simply wasn't intelligent enough.
Counterpoint: the Pak from the Known Space books. Terrifyingly intelligent, but regularly nuke themselves into the Stone age because they're as tribalistic and paranoid as they are smart.
Not exactly hard evidence, but we don't have many real world examples of alien civilizations.
If Larfleeze leaves Vega then he'll be invalidating it.
Huh, I suppose the Guardians never bothered with a clause of Larfleeze not leaving of his own will, because if someone could force him to do that then he's not much of a threat any longer. Comparatively, at least.
