Word on the street is that this is basically it for at least a few years.
'n that's a good thing. We have this because some human was able to write their dreams and ideas into being without obligation; compare this with trillions of reskinned shovelware and out-of-the-box "plug all the widgets in and call it good." If they can't run away from what they've been hunched over for a half-decade or so, we don't get that.
...on the other hand, the state of the game promises just a few bugfixes (mage targeting, for instance, sometimes goes really, really wierd. Someone's stabbing me and I'm firing into empty space, or someone else?), probably every now and then - a quick log check shows a lot of petty bugs and typos being swatted long after the "screw this, imma do this sequel now" announcement.
The game's content also suggests revisitation down the road. Three crystals, eh? A second level to the goblin mines, possibly connecting to Gorx, or worse? A whole ork kingdom over there? But... it is unlikely to be right now.
I... can almost promise you you haven't found all the content that's in here, not even a fraction. I'm moderately in the "back in my day, we didn't have" crowd for this game, and spent a lot of it locked on an old version - no ark, no wastes, no emerald valley, no mount oroog, just "here lies the end of the universe." I'm still finding new things that I deeply suspect were written in there very, very deliberately, and I suspect there's more, just on the old version.
I'd pay far more to read the game than to play it, and I consider it underpriced as a hack-and-slash without the content. Then again, if you check the downloads, there's a decent chance David, y'know, doesn't need us or anyone right now...
...but, this game will be a while. Poor man spent a year or two more hunched over it than he wanted to. I promise you, there's still at least a decade of new in there ready to discover.
I believe that many fans would even pay for more content
...that would be financial fraud across several states' jurisdictions under the liscense some of us early adopters got. I might buy the t-shirt or coffee-mug, though.
I honestly assume it is in fact coming. Let the man clear his head and follow his heart, or we'll just get crap, and things like this won't exist. Besides, the numbers suggest he would have no use for your money, anyways.
