It really seems like the sky is the limit with Elemental. It also sounds like the internal build is vastly farther along. Will beta 2 be pretty close to your internal build or is it still going to be pretty stripped down as far as content goes?
The entire point of advancing Beta a step (3 becomes 2, 4 becomes 3, 5 becomes 4) is because of the huge amounts of extra work they have to do to strip our version from their version. So for the most part, we will now be getting the internal build. Mostly, and this is as far as I've understood Brad correctly. If I haven't, I'm sure he'll be able to correct me.
So we now get most of the shiny stuff. We won't have:
Game editors of any sort (Tile, Particle, World builders)
Annnd. . .something else. I forget. Uh. . .*Digs about*
Right, right! Tactical battles. We don't get those yet either. Or naval warfare. . . Or the Elepedia (It's actually called the Hiergamenon, which I love, but feel weird cackling to an empty room).
But we get the rest of it. (3D engine, trade routes, Multiplayer, shops, sieges, "visual battles" [IE I think we get to watch, not touch. Not sure though])
