I really hope SH4 does not need the modders. If the game is properly made, without any bugs and with all the historical references in place then modding it will not be necessary (to the level GWX mod changed SH3 at least). That is a good thing because it means that in Ubisoft they take their job seriously and give us a good value for money program. Alas something is telling me that it will not happen
In any case my computer cannot cope with SH4 at the moment and I'm more interested in the Atlantic theater. Therefore it will be GWX all the way for me for quite some time
