Which is probabily why people think it's a scam, which it's not.

Most adults are paranoid about people stealing there money on the internet, but Data uses Plimus, a trusted purchasing site.

Besides, Cortex Command will be more expensive "when it's done" and you're best buying while it's cheap, then getting your money's worth when it gets better and more expensive.

And who knows when it's done?

It maybe worked on until the game's value rockets to $100+ !

I am still confused how Data thinks he can sell the game for more than 18 dollars. Apart from the die hard fans, 18 bucks is pushing it for an uncomplete indie game.
I think I heard around he was going to bump it up to 30, or 35 or something. Eh.

CC may be just an indie project, but it's the most addicting game I've ever played, and if I can buy myself a copy, I will (I am in the impossibility of buying it at the moment). Of course, the game is nowhere near completion, and we still don't know the official release date, but just for what it is now, the game's worth it. See it as a game that gets huge updates every half-year/year. And with the inclusion of LUA, the game's going to be even more worth it. Trust me, trust us, trust Data and his crew. It's worth the buy. Pixel Art like you've never seen. Physics that'll blow your mind. Sweet effects and explosions. A game you can make your own. That's what it is! I swear, since the day I first played a game of it, I've been hooked.

Tell your parents it's safe, and backed by a trusted download site. They probably won't understand that it rocks so much, but at least the secureness of it should pipe their worries down.
