I officially have more play time on uboat than i do any other title in my steam library.
the problem with the mods, is the dev team updates with a new patch / version every 30-90 days, and more often than not, especially when it comes to the more complex mods, the mods are not forward compatible so the mod now has to be reworked as is the case with the
PHENOMENAL TDC mod
This thing is starting to become more and more of a dream Uboat game every day.
