I didn't really set out to be a dice collector, but I just ended up with a bunch. First, it was just a set for me to use as a player. Then I started to DM some games and had to get more. Then one of the groups I was in had some players who didn't have enough dice to get by, so I set up several complete sets of different colors so everyone would know who was rolling what dice. Then they started making all those oddball dice like D30s and D18s and stuff like that, and I thought it would be cool to get a complete set of all those. Now, I just have a box with a bunch of dice bags all stuffed with dice....
