a long roll on an rpg die is just more time for the die to find its 'rut' caused by oddities in its shape. the fact that Game Science dice don't do this is a selling point.
and even then, just put a little more energy into rolling your dice and they'd tumble around just as much as a chessex.
Gamescience is a scam.
Plus, every single time you get a gamescience die, you have to sand off the extra elements that are always on them. It's like they were all molded on a large rack and then broken off, so there's extra bits of plastic on them, that you have to sand off. The end user sanding off plastic, doesn't sound like it would do a very good job at ensuring the dice get a scientific outcome.
If Chessex uses a process of: molding, then cutting, then polishing, then inking the numbers.
Gamescience only does two of those, then somehow tries to convince you its better.
Tech Sgt Lou Zocchi makes the best dice. by far. over anyone else i have bought dice from..
This used to be true, the company he sold off to however puts out inferior goods, with inferior materials.
That was indeed true; however, Lou recently bought the dice and manufacturing back (in part due to the complaints regarding increasingly poor quality, IIRC) and is working on getting GameScience dice back to where they were in terms of quality and production.

That's fantastic news. Looking around the net, though, the latest news I found was almost a year ago. Does Mr. Zocchi know about Kickstarter?
