I've played quite a bit of the latest Need For Speed, which is open world, and has some MMO content (and is one of the games in Origin Access), and I'm really happy I finally found a racing game like NFS Underground 2!
I find your dedication to that project amazing, and kinda inspiring! It's been a while since I started on an adventure like that, that I knew would take ages to complete :P I still have the 3000 pages novel I'm writing, but I kinda of set it aside to start my company.
If you're so pationnate about making games, have you ever thought about a career in game developpment?
For the project, I'm not really technically savvy, but if you have any gameplay, mechanics, or feedback related questions (or any other I could answer), feel free to ask!
