I haven't made one of these in a while so why not again.
If you had the ability to make your dream videogame(s) without having to worry about effort, copyright, or any limitations, what would you do?
I recently came up with an idea after playing a bit more of twisted-metal kinda car shooting games like gas guzzlers extreme and looking at this map I found on google images

(some route 66 travel map with other routes)
I was thinking it would be awesome if there were a multi-stage race between all these points while having 200+ vehicles all going at the same time ranging from buses to atvs to muscle cars to motorcycles to many other unique things while they shoot eachother with many many different kinds of weaponry.
But of course I would remove some of the points since some are too close together. And you may be thinking "200+ vehicles at once??? That's insane!!" well you're most definitely right, but I was thinking once someone is out, they're out for the whole thing. So by the last one there might only be a few left. And each stage would be moderately long (not as long as the actual route of course but maybe 5-10 minutes each) and between each stage you'd have a chance to upgrade and repair and fuel your vehicle and buy new weapons that get increasingly more deadly. Everyone starts out with standard car-mounted machine guns.
And then I'd make an alternate mode where everyone's fully upgraded and had unlimited fuel and other necessary stuff at the start, and no stops. It would obviously take a long time to complete but it would be interesting. I think the main problem with this though is that eventually everyone will be too spaced out from everyone else to do anything, so the other main mode would probably be more fun in general.
