It's the same as Team Fortress 2. On the Team Fortress 2 board on SPUF people are complaining about VALVe not fixing bugs and stuff.
When a game has internet connectivity on a PC or similar machine, there will be updates, new features and bug fixes regularly. When I first started playing TF2 hats were still relatively new and the engineer only had the golden wrench as an unlock.
Today, we have over 100 different hats (probably even more than that), the soldier has more unlocks than Jay Leno has cars (the engineer still has the short end of the stick in this case with only six weapons), there's an entire in-game subculture based on trading, you can purchase items in-game (with real money), and you can download the game for free.
I'm actually surprised how Trackmania hasn't changed much over the years. Yes, they have new environments, but that's all. No in-game economy that directly converts to a real-life currency, no unlockable content, no hats. Just you, the (likely player made) track, your friends, your custom painted car skin, and a taste of Web 2.0.
