Dude, you asked. And there's a reason I put it behind a spoiler tag.
The whole 'death gun' thing was retarded and makes 0 sense. The whole exaclibar arc was fucking pointless filler. Wasted a whole episode on recap too.
Just marathon'd S;G and that shit was spectacular star to finish.
Death Gun makes perfect sense (aside from the retarded name) if the point of it was to terrorize the gaming community.
S;G=Steins;Gate? That's actually next on my list after Ixion Saga DT. I love a good time travel story, but it's so hard to not fuck it up. Haven't seen a good one in almost 10 years.
