TWoS may be too hardcore for you, but there are means to play it in a simplified way, although the AI and sub damage is still at very high difficulty.
At some stage I will release my 'Stockgame Plus' release for SH5, everyone will be able to install it, u-play, steam etc...But currently I'm busy in SH4 and it will not be for tomorrow I guess.
Meanwhile, I suggest you install TWoS, have SH5 version 1.2.0 installed, better outside of steam and outside of Program Files (x86) folder, then apply the U-play fix, then install WoS.
Have fun!
