Even with that, my instinct is that the data base would be a lot of work for nothing, because if I wanted to search for all Heroclix, I could just go to a store that sells them all - and that is as simple as you linking it.
I just don't want you and maybe a few more people spinning wheels when it isn't necessary, especially when that effort could go into brainstorming for new cards and/or playtesting.
I greatly appreciate you setting this up btw. What ever you end up doing here, I am sure it will serve C3V and the community. Thanks.
