I have got an easy one. I would like to see a forum topic opened just for restorations. That way when someone starts a new restoration their progress could be enjoyed from start to finish. And everyone could learn different tips and tricks that people use while restoring a game. Only problem I can see is that I would probably be looking at it all of the time and never getting any actual work done.
I have a beat up, re-import, WCS that I have stripped completely down to nothing and am in the process of restoring now that I would put in there.
