I modified the ENB DLL's so that each uses its own set of unique files and surprisingly it worked right away! It became clear after a few weeks that the only solution was to use multiple ENB dll's at the same time to each give their own supported features. Looking into the graphical modification available it was clear that everyone had problems getting the decent effects working so I began looking into it myself. Unfortunately I do not own COD2 through steam so my screenshots cannot be uploaded. The only area it lacks compared to todays game is graphics.
It is just as enjoyable now as it was when it came out. Most games are somewhat underwhelming when you play them again after such a long time, but COD2 is not one of those. I still have fond epic memories of playing COD2 for the first time! I decided to dust off the box and give it another go. Call of Duty 2 is one of, if not the best Call of Duty game ever.
