Indeed. Personally speaking, I’d like to see at least the following ready in time for Steam early access:
-Balanced combat (!). I know there’ll be peaceful mode, but if it isn’t better balanced then early access release will just result in the forums being flooded in more “OMG GOBLINS!” threads, which won’t reflect well on Radiant.
-Terrain modification (ie digging steps etc), or failing that, at least ladders that go down as well as up.
-A whole bunch of bug fixes, especially the game-breaking kind. Villagers being reduced to just heads, crops that won’t harvest properly, wall o’ text error windows, that kind of thing.
