Can't be, that would be just stupid. AFAIK Raceroom hasn't been really succesful with free2play ghost timetrials, thats not what sim enthusiasts, the target audience, is looking for. First it looked gmotorish but the rest doesn't look like it. Probably they've taken a lot from gmotor to their new engine but that is the main thing we are waiting for, we don't care what the box say, we want Lizard! Or what-ever they decide to call it, i really have not be up to date with SimBin development lately. But from a modder point of view, nothing really radical, this all can be achieved with gmotor2 with some native code added like DX10/11 support so don't get your hopes up too much. The promo said "new technology" so i'm hoping that's not just an empty catchphrase, for me SimBin means precision and their own engine could be just wonderful. Not forgiving wonderful, which they water down a bit to get more casual gamers due to pressure from marketing department. Being a "mod company" mod support should be there too so best quality mods will take it to the level we all hope.. Which is somewhere closer to iRacing than NFS, but not far from predecessors, i hope.. GTR2 ->Race07 is very natural, you can spend days with GTR2 and hop right in Race07, within two laps you're in.
