I will add some more: Rain? Day/night transition? Actual fps with more than one car actually?(rf2 build 240-silverstone 3 cars and everything full i have same fps as AC tech demo actually that makes me really curios now and there is half of the game missing) pitstops? It might be that AC will have bit more easy modding tools but some people still dont get it actually that a car or track will never be done more easy with those tools, it might give you bit more easy ingame process but that is nothing from the work behind that. Tools provided by game dev are usually only ingame exporters and maybe in AC some physics tool but that doesnt makes it more modding friendly actually. But iit really does look great in that video. Somehow that game reminds me alot on shift2 actually.
