I haven't played SH4 all that much. Been playing SH3 with GWX instead...
however yesterday I finally got around to installing the 1.2 SH4 patch...
and...I was surprised...both pleasantly...and not...
The graphics look awesome, the gameplay bugs have been dealt with (no repeating missions yet) and it's still damned fun!
...downside...
try submerging and clicking on the bridge icon...I dare ya...
It's worse than the A crash...cause you want to go to periscope and if you miss click...CTD...bah...
