Who has been the best Dcer ever?

[Marshall]

3rd gen (ztage)
YinYin
Lauli
Nave
Fantasy Leaf
Lkjop
Somin
Sinow (maybe...?)

Also Alblaka...

you also forgot azriel, bp so many more ;o

forgetting Azriel deserves a slap on my face. I actually logged in again just to add his name. I omitted BP because I am not familiar with his DC work outside of backgrounds!

recreate anything created by anyone else

well... most of the people I have mentioned have pioneered in something more or less. Not familiar with Nave's stuff, but I am well aware that he incorporates HEX into DC in a proficient manner, so he's up there anyway. some might call it cheating, but I think it's part of modern DC. There are a huge bunch of others that I have yet to mention if we even take re-creation into account, but it is a bit pointless really, so I omitted them. The taking into account of all aspects of bugs caused by the engine can be echoed by Fantasy Leaf.
