I can agree. I'm thinking about buying Richard Burns Rally, which was made in 2004(?) and costs $9, all because the internet says its physics are more realistic than the silly Dirts that are coming out lately.
That's all nice but it's not the most important to me. More cars on track is something more important and that's not a graphical thing, per se. What I want to see is advances in AI, physics, animation etc. There are plenty of games I enjoy which look awful compared to current games. Graphics isn't everything.
