Goes to figure, my 3 favorite systems are WEGd6, SLA Industries (2d10) and Talislanta (d20).
Over the years they have mostly disappeared, but I still have a few left.
My current favorites are my blue marblized d20, my black/silver marblized d10s and my white/black pip d6s (simple, easy to read, and cheap!).
My all time favorite dice: My Dice.
I cannot stand using other peoples dice. It has nothing to do with any type of superstition, or germs, or anything like that. I just like to bring my own dice. I feel it is my responsibility as a player/GM to come prepared to the game.
This includes: pencil, paper, book (if possible) and, above all, dice.
I also expect the same from my players/GMs. I hate having to loan out dice, that is why so many of my dice have gone missing over the years.
New players are an exception, I expect to provide them with anything they need to play. If they decide to continue with RPGs, they can get their own dice at that time.
