How the hell did it turn from interesting topic to who's more screwed in life by tragic situations and living normally now?
I mean seriously people.
It is offensive, and it has the wrong concept here. because once you die, in real life, you're gone, forever. And those people (kamikaze, terrorists) made their choices knowing they're gone after that forever. (one of more popular questions is why do kamikazis wear helmets, right? ^_^)
So I'm asking you, how will you balance this? You want something small and powerful (think suicide scourges from starcraft), but you want to respawn and do it all again then.
cloning? maybe, sure go ahead, but I can't see spawning in the same expensive ship later.
Maybe starflea as the ship and some "explosives" as ammunition, that are few mil expensive, so when you die, you lose it all.
