I really need to know should I install SoaSE update in order to install entrenchment or I may ignore it and install entrenchment directly (after installing SoaSE of course) ?!!
Sins 1.15 is required for Entrenchment. So make sure you have Sins updated before you install.
but i have a french version of "sins of a solar empire" , i want to know if there is a french version of "Sins of a Solar Empire: Entrenchment " or if i must wait or if this two version are compatible, thanks for your answer, and sorry for my mistakes
Yes, there is a French version. It should install automatically if it picks up a French Sins installation. But, if you want to double check (and it would probably be a good idea), send an email to firstname.lastname@example.org so they can tell you more officially. I tried to find out exactly how it works last night, but no SD person who tolerates me bugging them was around.
