I commented last week that I hadn't been playing any DG until the 1.2 patch came out. I figured there was a substantial number of people, like me, waiting for the patch. The new DG's are obviously a draw, but I think the real appeal is the modding support coming online. I've noticed several dormant modders from the beta days resurfacing.
If dev support for the game stays strong, modders start getting their groove on and holiday sales come together this game could see a strong resurgence.
