Untill patch 1.2 was released it was unplayable...
After 1.3 patch will be released buying it is a must!
Even with 1.2 patch it is in OK/good status.
If you are good in elementary math you will enjoy manual targeting as I do.
When patch 1.3 will add some features like
“assisted method” to determine the target’s speed when playing with the manual targeting option set to “ON”, to simulate the firing party putting together subsequent range checks from the captain and solve some bugs like ship dimensions in the game config files,small conversion error with the stadimeter when using “imperial system” , the submarine radars (SD, SJ) bugs, campaign retirement bug and AI behaviour improvement the SH4 will worth all bucks u spend on it.
* AI impromement was made by beautiful mods of sirs Beery and Decimious
.
They made brilliant patches, even too brilliant :-)
Bottomline: After 1.3 will released and with Beery/Decimous & Co works Wolves of the Pacific is the simulator you must to have on your PC.
