When the U-Boat Missions Expansion for SH4 was released, people said SH3 was dead.
When the Grey Wolves announced GWX 2 was the final release for SH3, people said SH3 was dead.
When the Grey Wolves announced work on GWX 4 for SH4 had begun, people said SH3 was dead.
Notice a pattern?
For a game that has been pronounced "dead" for two years it sure seems to still be going strong and it will continue to do so for as long as there are modders out there who continue to improve this game. The full potential of what can be done has barely been tapped, especially with tools like S3D out there now.
Every modder who ever said SH3 is dead or that everything has been done for mods that can be done either lacks interest or imagination enough to continue working on the best sub sim ever made.
