It is far too early for a 1.0 release. What about new terrains, quest/story, more enemy types, weapon types, mechanics(?) and possibly some other things? Right now the game is extremely small and you can get through really all of the major content in about a hour and a half. The game feels more in alpha and would feel wrong to basically skip all of the way to full release already. With the game set at $15 it is already far more costly than the content is has right now, and if a couple things that can be done within a short time gets it to 1.0 doesn't seem right at all!
