I'm mostly interested in these three:

Stealer
It was cancelled at one point, but it seems like it's under development again.

Project Zomboid
Of the three I'm following this one the closest. Progress seems a bit slow, but at least it's consistent. I suspect that a lot of developing time is going into the most anticipated and asked for feature : npcs.

Starsector
I love these kind of games, but I haven't played one yet that, well, ticks all of the right boxes so to speak. I enjoyed SPAZ a great deal but the incredibly weak story, voice acting and unsatisfying conclusion to the game was a downer. The 'world' wasn't that convincing either, and it didn't feel like there was much significance to anything I was doing in the game. At least in this latter sense Endless Sky is a whole lot better. But it suffers from overly chaotic combat where you can die in an instant without much of any idea as to who/what actually killed you. The trading system is bit too simple as well, since every single planet has the exact same items to trade, about 10 types, and the only difference is the buying and selling price at each location.

i just dont care anymore
if a game i am interested in suddenly appears in the stores
great

if not ..whatever

Generally, I don't follow any games that are still in development. Not even the ones that interest me more such as Divinity 2 or Tides of Numenera. I'm just waiting for them to get released when the time comes. :)

I can't say I really follow the development of any games any more. I used to a bit when I still got Nintendo based magazines (before they all got cancelled) but these days while there may be a few games I am aware of (Zelda Wii U, Divinity 2) there are not many I would buy day 1 any more (Zelda probably being the exception) so following the development doesn't really seem worth it...

M. O. R. E.

But I'm not very hopeful about it.

I'm not even aware of any games in development.
They'll come out when they come out and maybe I'll buy them and maybe I won't.

I've been watching Stardew Valley for a couple years. It's like Harvest Moon and with the amount of love the dev has put into this it should blow the other couple of games like harvest Moon on PC out of the water.

And I think Transcendence is essentially done, but it continues to receive updates:

So this is why they haven't unbundled the old versions that's included in the 2004 game?

Blitzkrieg 3 kinda. I look into it every here and again to see if it is released released yet.

The newest Zelda, hopefully on Wii U or else I just don't get it. I don't let myself get too hyped for it but I still get a bug to look into it every here and again.

Anything Monolith Soft happens to be up to. Every here and again they mention they're working on a new RPG and I look forward to any time they release some more information.

Edit: You know, I just remembered, but I also like reading up on Scalebound even though I most likely won't get an Xbox One at all. I really like what I read about it, though, and have enjoyed all of the Platinum Games that I have tried.

Pretty much only this:
Grim Dawn
