So..., essentially this is where we list what's been wrong with GT thus far and missing thus far as things we want them to fix for GT7.
The Gran Turismo franchise's glory days wherein it was the top racing series available for game consoles are long, long gone, and this will never improve until certain things are fixed. The best physics in the world don't matter if the rest of the product is mediocre. The most massive car list in the world is underwhelming if most of it is clearly outdated, sub-par, recycled content (like 80% of the cars in GT5.) Looking pretty (regarding the new content, as content from previous generations aren't pretty) is offset by sounding like crap. Going through a list and ticking the check boxes for the short list of minimum requirements for being a driving game while doing little in the way of going above and beyond the basics doesn't make for a genre-leading product.
- No recycled car models. This means no 1000+ cars because they can't produce anywhere near that many cars from scratch in under a decade, especially not at a PS4 detail level. Kids will have to suffer crying about 100 or 200 cars, but at least they will be proper PS4 car models and not old sub-par junk imported from a decade earlier. PS3 content won't even cut it.
- Proper car audio. As long as people can mock the cars for sounding like vacuum cleaners, it's hard for people to respect the game.
- Actual racing. No rolling starts; at least not unless it's replicating a real-world series that actually uses rolling starts. No parade of cars strung out half a mile ahead of you and you being tasked with just casually driving by them one-by-one. We need standing grid starts and AI that acts more like humans and less like robots intending to simply pose as mobile chicanes.
- Features beyond just physics, cars, and tracks. This means stuff like the long-desired livery editor.
- Mechanical damage available in all game modes. If you aren't at least making some sort of effort at simulating what happens when a car smashes into another car or into a wall, you aren't a simulator. Period. Inaccurate damage is still more realistic than none at all.
- Get rid of tedious bullcrap. Oil changes add absolutely nothing to anyone's gameplay experience. We know cars need oil, just as they need a lot of other maintenance. Why stop at oil changes? Why not make us replace spark plugs, wiper blades, brake pads, worn tires, transmission fluid, brake fluid, et cetera? Oh, and don't forget that we need to put fuel into the tank. Maybe we could not just wash the exterior but also vacuum the interior. Heck, we already have the vacuum sound effects.
