You actually plan to finish the map? That's ambitious! I'd advise against it though until you've improved the car handling, honestly. That way people can enjoy driving around the roads of the map that are already there. Maybe ramp up the acceleration/brakes, gravity... then again, I tried Unity once and was never able to get the hang of typing actual code.
I'll not finish the entire map, but just finish Portland, there are a lot of unfinished areas in my demake.
I now have a bit more experience with car physics thanks to other side projects. I think the main things I need to do is lower the center of gravity with a few tweaks on the car's acceleration, and make the wheels less slippery.
I think when I'll have a bit more free time I'll fix everything and finish the map in a big update, to at least have a fun and playable demake.
Hey! So I played the game again, spending about an hour to get 27 hidden packages. Had to look up a guide for the 28th one :P Very dissapointed there's no congratulation, but I can understand, it's still unfinished. I'll say, this really keeps what GTA III was to me, since I often just hunt for hidden packages while putting other music in the background. It's a relaxing way to spend the time back then - doing it in this demake was stressful though since I'm a lot busier now ahaha. Good demake! Definitely will await that update, with better car physics.
