Hi Schifty, this mod looks great and I'm delighted you're making it, however I have a few suggestions and some feedback for you (please don't take any of this personally, btw)....
1) Will you make the correct car shapes for the 1994 cars? It looks like you're using the 2011 car shapes, with 1994 liveries.
2) Will you make the wheelbase wider, since in 1994 the cars were wider track?
3) Will you make the 1994 cockpits?
4) Will you make the helmets the correct shape for the 1994 ones? The shapes you are using are the 2011 shapes, but in 1994 the helmets were rounder.
5) The HANS device was not in use in 1994....so can that be taken out?
6) Can you make the 1994 circuits, with the correct advertising boards, etc?
7) Can you make a 1994 style driver's monitor screen (when you are sat in the pits in the car waiting to qualify and looking at the screen to see the other drivers' times). They did not have flat screen monitors in 1994, but they used the big bulky tv screens.
8) There are also some pictures of laptops and flat screens in some of the screenshots...but these weren't around in 1994, so can they be taken out to make it look more realistic?
