1) I tested Fo:DE and i am afraid of that player would not fully populate whole Europe wasteland. Those maps are too huge (many of them) and players will be dissapointed. Did you considered, that you can open up all locations not from the beginning of the open beta, but from time to time, depending on server population?
2) Surf.. only perfect graphic design of objects will not create good game. Look at 2238. I understand that many player suggested (and created) maps, objects. They were refused by Lexx, because they were not in harmony with Lexx and other devs visions. It results into state, that whole Fonline 2238 project is 100 percent their vision, but last 1,5 year, without any major update (except Glow "dungeon").
Fonline 2238 harvests popularity from well known F1,2 locations, selling players illusion mixed from old Fallout atmosphere and nostalgy. Players taste it and left, or group together and fight each other (gangs). Second group wishes were too longer ignored, so dont be confused, that new projects, even not fully perfect in your eyes, but giving players the needed response, are welcome.
3) I hope that your project will overcome basic childhood complaints and you will not loose your spirit and finally, THAT YOU WILL NOT REMOVE OLD COLOURIZING, BECAUSE IT IS THE REASON WHY EVERYBODY LEAVES SERVER.
