Do you agree with me?

Which one of them should i buy? which of them is better? like 5 years ago i played trackmania but i dont remember which one it was. but it was not turbo or lagoon, any older one. I just want to have a fun racing game. if i want to have it realistic i will play need for speed etc....

I've downloaded the demo via Steam, but all I get is an endless flight over a cloudy sky and some neat music, but no game.. no key except ESC does anything, there's no menu, nothing..

If not, why won't they do it? I know it's so you can go fullspeed at start, but this should be an option.

Why is Lagoon even a game though? This game is 4 years old and they released TrackMania Turbo, but more to the point: is it worth buying?
