While I understand your point and I certainly can't say you are wrong I would disagree.
A new location would require new textures, trees, and scenery while a new stage could reuse a lot of these resources. And I certainly hope when the team went to the locations to research them they looked at multiple options just incase there first one wasn't what they were hoping for.
Rally games have traditionally marketed there quality on number of stages and total stage length in the game, weather it is 12 locations with 24 stages (like we have now) or 6 locations with 24 stages would amount to the same press release and marketing. My issue is I only drive full rallies using only the long stages repeated and reversed for a 12 stage rally to make a challenging event, so more stages would make it more interesting. A new location with 2 stages would still mean repeating the same stages more than is preferred but would mean a longer championship. So personally more stages is what I'm after.
However, I hope ONE of us is right as more content is more content and that makes me happy.
Stages, locations and old or new cars, I don't really care. Just want to get my hands on more rally stuff.
