Since they were Shockwave based games they're not playable on modern browsers but they're playable with the Flashpoint Archive project. Huge timewaster, be careful. Better look for the games on YouTube :)
And thanks for the game names as wel, although, I must admit that after posting that comment, I did go looking for them, and... Well, let's just say I've found my MixMaster skills to be quite rusty after all this time :p
What a shame CN took their classic game sites down, when hosting flash games isn't even all that resource-intensive. An archive by them would've been nice. I recall every couple of years, older games slowly got removed which made me sad, until eventually flash died completely.
My goodness, I've come so far now in life. I know what tools to use to decompile flash games and look at the assets and logic, it's crazy to look back on how much games inspired me to learn about programming because I wanted to make my own.
To anyone who worked on these, thank you SO MUCH for having built them; you've definitely had a positive influence on countless people who were mentally stimulated and learned about how to use computers more in an effort to play them.

Though that's an interesting point: some games were localized on the Brazilian CN website! Not all, but it's cool that at least some of them were.
