hfc2x put in a nutshell when he said "Yet another An attempt to recreate Doom according to Tom Hall's original vision", but this time, chances are pretty high that someone makes it the right way. A lot of work has already been spent into this and as of now, the preview video is really interesting and impressing. You should take a closer look at the development thread at ZDoom and also give him a bit of feedback and thoughts, I am sure he will be glad about it. You can also find firther information on the current project status and progress here btw.
