I pre-ordered
Overgrowth some time ago.
It has been in slow-but-visibly-progressing perpetual alpha its whole existence.
The makers have thrown in a bunch of other games as bonuses for pre-orderers, but these were also alphas, though some of them have received updates after some time.
I can appreciate this, but while they're moving FORWARD they still have not FINISHED anything. And while I liked Lugaru (which Overgrowth is a sequel to) if I had known what an ungodly long time the sequel would take to be completed I probably would never have pre-ordered Overgrowth, just simply because most of the updates are more of interest to somewhat more obsessive modders than to people who just want the game.
They say they make the bonus games as breathers from working on Overgrowth all the time, and I believe them, but I'm just...I dunno, something about it rubs me the wrong way.
EDIT: On the other hand, given they're making the entire engine nearly from scratch for all three major operating systems, I guess it's *somewhat* more understandable why it's taking so long. At any rate they do communicate very openly and clearly with their fans/fellow coders/partners in crime, which is good, and is more than I can say for how Gearbox treated people who pre-ordered Colonial Marines.
EDIT #2: That much said, probably not going to pre-order anything from the Project Zomboid folk again anytime soon.
