Wow, TSR released TSR workshop for The sims4 version! This version(v220.127.116.11) is able to work in TS3 and TS4 both. It’s really usefull. I don’t try it yet. But I hope that many wonderful Sims4 contents will born from there. :)
P.S. When unzip it, my anti virus software found a virus (win32:evo-gen). Probably I guess it’s a misdetection.
