FSX/P3D. Actually, I am not really sure on how to fully describe the latest announcement by REX Game Studios. I'll say this: These guys are working on some very big things. That is, big and plentiful. Today's announcement regarding the new REX4 line of products will give you more options and features than ever before. Most notably of which is the upcoming REX4 Weather Architect which will be focused on User-Controlled Weather Generation. Again, I could try to explain it all, but you are much better off tapping the source link below. Damn, I still don't even have REX4 yet. I really need to get on that! Thanks to ADX Reader Tim Fuchs for the tipoff!
