Once again Indie royal is testing my patience. Coming off the overspending of Christmas and the Steam sale, now Indie Royal is putting up Nuclear dawn in their latest bundle of games. Also included:
Max & The Magic Marker (Never heard of it)
Fractal (think I've heard of it, iirc its supposed to be good?)
Super Crossfire (never heard of it)

As of writing this, it is $4.11. Super Crossfire does not come with a steam key, but everything else will.
The New Year's Bundle - Indie Royale

If you haven't heard of Indie Royal before, basically think of the Humble bundle with a changing price and no charity. Basically a (I guess fairly large) site dedicated to indie games set up Indie Royal as a way to spotlight indie titles they believe are well great games worth playing. The money just goes to them and the developers.

The quicker you buy it, the better. After it comes out at the initial price, the price will go up every time someone buys the bundle for the minimum or close to it. If you pay way over the minimum though, it will drop the price the minimum price. Thus, unless you are planning to beat the minimum (or have a certain price in mind), it is best to buy it early before the price climbs way up. As an example, in the time I've spent writing this its gone from 4.08, to 4.13, down to 4.09 and back up to 4.12. Over a few hours though I've seen it sometimes go from say 4.11, to 5.11 (as an example).
