Dungeons & Dragons new iteration is coming. How soon is too soon for mew editions? Has it even been 4 years since 4th was out. If 5th, or whatever they are going to call it comes now, how long before 6th comes after that? I`m all for new editions in due time, but I`m also for stability of a lasting system or the timelessness of an old "retro" system. Any thoughts?
