I think I read on Facebook that Splash and Go closed up shop for good.
EDIT: From the Splash and Go Facebook page:
Hey guys, Cosmin here.
As some of you have noticed already, our website is now down. It will be down for good. In the last few months I've been too busy and honestly have completely lost interest in adding more content like the previous one to it.
SNG will no longer be making mods. It was a pretty painful and stressful process for me to learn all that and apply it in the way i wanted. The limitations are too much and just pissed me off more than anything.
I hope you guys enjoyed our content, I hope to see someone pick up on the possibilities left unexplored and please take our work as an example of what can and can't be done. I'm very thankful to everyone helping out along the way, for the support, feedback and critique for our "mods".
I'd personally like to thank everyone who helped make my job easier by making the templates, textures, car paint schemes and to everyone outside of our team that helped me out with writing everything in the game itself. (that was the non-fun part) Any help i got is greatly appreciated.
I am very proud of what we were able to achieve and i couldn't have done any it without everyone else's help.
The files that were up there will be hosted somewhere soon as well. Stunod already offered to host them on their website.
TL DR: No more NR2003 mods, they'll be uploaded somewhere, thanks to everyone! , paints only. requests or tradingpaints publics.
