Yush, tittle say all, i just wondering ask this just beacuse, if modders try to mod this a game thease new dlc allways broken their mod so, i just want to first to know how many dlc there will be so, im not start or do too much work with thease modding project just beacuse this uncompared possiblity & reason. Ofcourse i like to have & see lots of dlc but, that not was good for game modders.
