I've had the game for just over a week now and have been playing it to death. It's a very elegant game and I love it.
Apart from a fix for an intermittent, but fairly regular interface disabling bug that doesn't allow you to save/reload, nor continue (you have to terminate through the task manager), the game runs really well. The bug usally happens after I've inadvertently clicked one of the side buttons on my mouse and everything hangs - although the task manager tells me the game is running.
I can send my current save game, but that is a couple of turns before the bug struck... something to do with something being outside an array... technical stuff no doubt - I just play 'em.
I can carry on playing until the game crashes again. I can then screensave the exact message and send the most recent save to you for you to work your magic on, if you wish?
As to the nice features bit, which would all work very well as an on/off preference. These would be very convenient for players:
1. An autosave option for the end of each turn;
2. An undo key for when you unintentionally have clicked a unit in move mode, forget to click off, but then browse another unit. This results in the original unit moving towards the browsed unit..., which is frustrating. Obviously, if the move reveals a hidden unit the player shouldn't get the benefit of an undo. It would make the game more forgiving for dozy characters like me though...;
3. A highlight feature for all units in a formation when you click on a unit. Sometimes its hard to find units in a formation oob when they're scattered all over the place.
That's it. BTW I'm seriously thinking of picking up ATG if it's anything like DC WtP.
