can't you just download a c++ compiler and some libraries and start making a game? how does that cost money?
ides worth a damn cost money, places to live cost money, meals. The devs don't live in their parent's basement. They're adults.
I would still play Blockland at 1.0, it was a good game, Badspot updating it made it even better, he didn't have to do it, but the community appreciates it. TF2 also didn't really need content updates, in fact, it pretty much invented giant free content updates within games that aren't mmos.
The FTL guys didn't promise these updates, so don't see why you're whining because you don't have them.
