peoplepeople...
rlly i heard u talking about taking a quick jump to your planet then blowing it up with a superwweaopon.
indeed this sounds onnoying since there's litle u can do about it.
tough i never heard anyone say how long this... superweaopon has to charge before actualy firing?
i mean... u cant suspect somthing with the power to blow, or kil the planet's surface works like a simple pistol... pul the trigger and boom...
more like pul the trigger, wait 30 or more seconds then a shot.
also, the power to "destroy" (in term's of blowing it to 1.000.000 bits and pieces)
cannot be done from the surface. u would have to get some sort of supernuke in the planet's core. eve nthen u'll end up with a few big plates flying loose..., (imagine europe flying by

since it's rather dificult getting to the planet's core from outer space, "destroying" a planet would feel more like vaporizing the surface (and anything burried).
the siege frigate's nukes help alot with "blowing" the surface. tough a superweaopon that chain react's the planet's atmosphere would be cathastrophic, since nothing but the deepest bunker would survive,
even if the guys in the bunker manage 2 come out the infrastructure on the planet = gone and u seriously hit the oponents economy
if i think of a planetkilling weaopon i am actualy thinking about destroying the enemy on the planet, not the planet itself.
this concludes my opinion on the Superweaopon thingy

now 2 start on the N-BOMB thingy,
the further away the detonation the larger the radius, example: detonate N-bomb 30 miles above the US and u black out 95% of the US
detonate N-Bomb near edge of atmosphere and u'll probably black out 40 to 50% of the planet
since the electronic shockwave is wider then the planet when it contacts the planet it hit's the surface in a circle, and since the planet is round (at least i hope)u'll hit 40 to 50%
now (finaly) i;m new here... sow i'll all give u a nice HI
