Rogue Space is almost 2 months old now and the reviews are pretty damn good. For something that started as an 8 page pocket mod, it grew into a 64 page RPG...but retained all the simplicity and flexibility of the source rules.
You can read some reviews and a podcast look at the game, including using it for a Mass Effect RPG engine at the following links.

....and if any of that intrigues you, check out the free 8 pg core rules on the Rogue Space blog or buy the game for $7.10 at Lulu. I make ZERO profit from the sales, but if you like it and want to donate to future exploration you can do so on my Rogue Space blog.
