Watkins is done deal for me, no objection for it's use.. For Moscow, well, someone could try it and give their honest opinion. We can increase the fun factor without any need for cutting down realism. Apart from locations, while it's nice to have a track bearby, i don't really think that should play as big part as it does now. Track type and style should be more important, so that if it's street track that we are missing, we drive on a street circuit.
There's tracks in the game itself too that we have not driven on. They should be super easy for all since we have driven on them all. We are missing Hockenheim, why don't we drive that and not the Russian GP? It comes with FormulaRR free package, i think it's default DLC now so it should automatically installed (and thus no one need to download anything...) Good for promotion, we could maybe try get RD Hockenheim week, with one F3000 event that is co-hosted and features lots of PrestoGP drivers? Going for maximum potential element here, extract everything out of that special situation: We have pretty recent official version of Hockenheim that is pretty effing accurate on every Race07 install..
EDIT: Funny how Hockenheim, a track that i have never liked is up there but that actually does sound good and fun place to drive now. It's flat like Sochi at least, about same length, similar layout.. And i used to like places like Watkins.. oh well...
