Subset Games today released a small update to FTL: Faster Than Light, finally giving it some Steam Achievements after the original release in 2012.
FTL did already have its own built-in achievements but now it's all nicely hooked up with the Steam API so you can show off how good you are. Not me though, I think I only ever had one successful run of it. Absolutely brilliant game though, a real devil with your time as you just want one more run.
FTL is actually one of the earliest success stories, especially for Linux gaming too, that came from a Kickstarter campaign. When they launched it, they had a tiny goal of $10,000 which was smashed ending on $200,542. This was before the likes of Wasteland 2, the Ouya, Planetary Annihilation and a ton more that eventually followed went to crowdfunding too.
