Overlapping Kojima games?
Posted: Sat Feb 11, 2006 8:29 am
I was just wondering if we could make a list of all the times different Kojima series overlap? It always interests me when he does this, so I thought other fans may appreciate a list of every reference to another series in each Hideo Kojima game. The list has grown considerably since it started, but there are still many games left to investigate. If you've noticed anything that isn't on this list that you think may be suitable, feel free to mention it in a reply.
