actually i agree with you guys it varies.
For my play style, i prefer everything as realistic as possible except for the Manual targeting which for god know why, i just can't get everything to works and my calculation is slow. LOL. It all happens back in SH3 days where i spend weeks trying to learn to manual target and eventually i gave up figuring its really not my forte. So ya, everything else except manual targeting and external view because i love to view those boats and ships to enjoy their beauty. But i never use it to scout the surrounding.
So now know 2 mods to enhance/fix the game while the other 2 mods fixes the gameplay. I guess thats all i need because afterall, this is my first play through.
