Interesting(ish) latest tweets about beginning multiplayer testing and working on AI, and no multiplayer demo.
AI is there for when there is no online racing available, or worth bothering with. The fact they they're only just testing the multiplayer is not filling me with optimism and I think it shows a real lack of confidence in the product to not release a multiplayer demo, it's what we all want to try. If I had made a brilliant online system, I would say "AI can wait, online is what we're about, and this is how good it is, try our demo". Pretty much what LFS did.
I don't see why you wouldn't release a demo of it if it's good enough to impress today's sim racers.
