Yep, there's your reason.
At least get the patched version 1.4 for your game. Cost's nothing....get it from UbiSoft, or from the "Downloads" section here at SubSim.
Steam is
screwing everyone into purchasing a poor version of SH4 when it gives you version 1.3!!! Then they act like they will do you a favor to offer the 1.5 U-Boat Missions AT AN EXTRA COST!!
SCREW THEM!!
Get a
DVD "Gold Edition" version 1.5 at iNetVideo for under 20 dollars.... delivered (when I bought mine, it came in less than 5 days).
This is
not a download!!
