Rappelons qu'ED n'est pas une association de bénévoles, c'est une entreprise qui doit gagner de l'argent pour pouvoir payer ses employés.We will have three purchase option to give customers, well… options. I’m sure most will go for the pre-purchase bundle option which includes the map and assets pack and is still less than the NTTR map. It’s best deal and makes the most sense for both single player and MP customers that are looking for the WWII experience. However, there will be a few people who want the map but not the units, and some that want the units but the map. The stand-alone options cater to those folks.
As mentioned though, a massive amount of time and cost has gone into, and will continue to go into, the assets pack. As the DCSW base is a freeware product, there must be means to recoup development costs at that level (aircraft modules are a different matter). It’s not a case of being greedy or anything like that. It’s a simple matter of having at least neutral ROI in which we can keep the lights on and develop future products. There is only so much we can give away for free.

Les joueurs n'ayant pas le pack ne pourrons pas rejoindre une partie qui héberge le pack
