In case it doesn't immediately show, I have no idea how the "behind the scenes" of the game works. Barn doors on the D-Series like the Roamer has. Short frame D-Series don't have a cap, but it is one piece instead like Chevy Suburbans, and Ford Excursions Different varieties of diesel engines for the D-Series, M-Series, and T-Series (but of different brands like Cummins, Cat, Detroit but fictional) Cammed V8s should have a lope (horse gallop) when they idle. The way I imagine is little revs for big cams, or a different idle sound for mild ones Maybe carburetor adjustments such as idle, rich/lean fuel mix and different brands of carburetors/different styles. Four barrels can have lag. Best way I can describe it is when you stomp it from an idle, instead of taking off right away, it bogs slightly before the other two barrels open and give you full throttle. Different kinds of injection like Throttle Body Injection Weather cycles like rain and thunder (I seen the rain particles in the world editor and thought it looked cool) Snow in areas like East Coast on and off (seasons of spring, summer, winter, and fall) The trees could turn orange and have leaves falling off them as a particle effect. Lightning shoots from clouds as a sky texture animation with blue/white flashes matching and delayed thunder. Roads get really slippery at first and then less slippery as it starts to really rain. Building windows, billboards, street lamps, and bus stops light up bright at night Equipment such as skidsteers, loaders, and excavators, and forklifts with equipment trailer of bumperpull, gooseneck, and T-Series variants for hauling to job sites, and maybe operating in freeroam, or using to load a trailer with ratchet straps built in the sides (flatbed trailer) or visible ratchet straps you can apply with the node editor Boats being driven in the water whether they're real vehicles you can hit, or low res animations for scenery. Airplanes too Travelling to different locations in career using the big four lane highway that is blocked off having exits with different map names on them. For example, you could go to east coast exit, it loads the map and spawns you in with the vehicle/trailer, pick up a load of planks from the sawmill, and drop it off at the city construction site. Purchasing of properties to spawn at with an openable garage/workshop. I want the farm house in East Coast with a garage. I love that house. Also, some kind of 90s to 2000s American sports car like a 2009 Corvette, 1995 Z28 Camaro, 2010 Challenger, 2001 Mustang SVT Cobra. Some kind of soft top convertible Airports to fly to Italy or any other out of continent map and the option to ship your vehicles for a fee Vehicles deteriorate after being beaten consistently. Lifter ticks, reduced performance, engine knocking, misfire, and faulty automatic transmissions/slipping clutches cannot be fixed with repair. Automatic transmissions can overheat, and slip. Reverse or drive can hesitate, clunk into gear, or be Neutral in disguise. Heavy duty automatic transmissions. 6.9 big block can blow the small stick/auto transmissions. Towing/performance shift solenoids to prevent clutches from overheating. Automatic (electric shift) that requires a computer and shift solenoids, and automatic (fluid pressure shift) that doesn't Thanks
