I would think 1.1 should concentrate on the relatively easy-to-do improvements and updates. Your list is good, although I think a "factor of 10" is maybe too much of a favor boost. over 1,000 favor for a single match? Maybe a factor of... 5 or 6. Concede, smart-quitting, and random demigod choice are all great ideas.
Okay, so, the wishlist for 1.1:
1. A tutorial. Seriously. We've all heard it before, the cries of the community and reviewers were not wrong. It will help with long-term sales. Make it happen. This is the hardest 1.1 improvement to make, resource-wise, but it needs to be done and post-release is not too late.
2. Clickable mini-map.
3. An option to not have the view zoomed/rotated when you respawn. I'm tired of fixing it after every death.
4. Click column heads in the custom game browser to sort by that column.
5. Add a separate small column with a lock icon to indicate password protected games. The asterisk in the player count is a terribly unintuitive way to handle this.
6. Fix the audio bug that seems related to the opening movies. Adding the command-line parameter is good, but nobody should have to look up how to do that.
7. Let players know the map and gametype of a Pantheon game before they choose their demigod. They still have to pick the proper light/dark side, of course. But if it's a Fortress battle, I might want someone different than if it's Conquest.
8. The game is forgetful. It should remember which health-bar state I last used (the ~ key) from match to match, even after I shut down and restart the game. Ditto with the custom game sorting (see #4). Ditto with map zoom and orientation.
9. Improved in-game chat interface. Voice chat is obviously vastly preferable, and there's tons of good middleware out there to integrate into Impulse. But that's a bit large for a 1.1 feature. in-game chat disappears too quickly, needs team/all color coding, needs better size and position, etc.
Oh, and Favor is busted. It goes without saying that, before 1.1, we should have the game as it exists now fixed to working order. Neither myself nor anyone I have played with all weekend has had their Favor actually update.
