Really looking forward to this and hearing that it will be open to modding is a big relief. In fact I'll just come out and say that I'm almost certain the vanilla game will not be as good as what we currently have out there now in the STALKER community with total conversions like Anomaly.
However if it is easy enough to mod this could be fantastic. The STALKER community is just so dedicated to the original games that it can't help but get at lot of love and attention.
I'm still playing Anomaly all the time, there just isn't anything else out there like it. While Anomaly continues to get developed, there is also a whole community of modders making content and mods just for Anomaly it's self. The depth custom builds you can experiment with is just staggering.
If anyone wants to get into Anomaly just give me a shout, as it can be quite overwhelming as a newbie.
By the way it's completely
