Eden Star is the perfect game for those of who have always wanted to play Mass Effect, but we're put off because there wasn't enough Minecraft in it. A first-person game by indie team Flix Interactive, Eden Star is described as an "immersive first-person, survival creation game that blends innovative physics based combat, destructible environments, and freeform construction with the exploration of a hostile alien world."
In other words, it's a first-person game where you don't just kill stuff, but can also build stuff and smash stuff.
Looks cool! There's a pre-alpha on Steam Greenlight if you want to see more.
