Guess I should clarify what I meant.
I don't like Shadowrun because the way that dice pools work well is in a few dice, about 5-7. However, in Shadowrun, I've never had a player, even with modifiers, who rolled under 9. Futhermore, the people who put the effort in character generation roll somewhere around 18 dice. It's hard enough to get players to focus on the damn game without counting out (And losing) 18 dice every time they want to do something.
Furthermore, Modifiers are WAAAAAYYYYY too numerous. For shooting your gun, you have to factor in range, recoil (more for burst fire!), visibility, and cover. You can't just raise the number of hits needed, because it's an opposed test. I think it's much easier to roll one die than 15, but maybe I'm more of a roleplayer than a rollplayer.
Also, 6-sided are my least favorite die of them all. At least 4-sided can be used as caltrops in a pinch.
