As far as me and sl1982 go, we are using the same resize tool and originally we were going to do this project together, but we ended up using slightly different post processing methods to clean up the images further and so we decided, for the sake of continuity, that we would keep the projects seperate.
Since that decision I have changed my post processing technique to be a little more similar to his but honestly the difference is still noticeable, mostly because he is adding grain where I am reducing noise. However we decided to start at opposite ends of the game, to encourage the end user to combine our projects together to get a finished product faster. However where I am sitting now, I think I am just going to finish the entire game using my method. That's not to say that sl1982 hasn't been a tremendous help with troubleshooting and helping me get started.
