First off I wouldn't be so harsh on yourselves.
Fact, the game is TURN Based ie NONE of the moron behaviour of real time strategy (of which I could rag on endlessly all damned day). They've been churning out those things for a long time, and let me tell you, they almost seem to never learn at all.
I am not expecting the game to be perfect on day 1, and no one else should be.
Steel Panthers, Combat Mission, Close Combat some of the biggest pillars of computer wargaming ALL have some aspects that make a person scratch there head and say WTF? I do not require Team Assault to be better than these wargame giants. And certainly not on it's opening weekend.
I have seen all manner of hysterical reaction to Battle Academy's 'cartoon look' a comment totally unwarranted, and as far as I am concerned, Battle Academy is the best computer wargame made since I discovered Steel Panthers in the late 90s. Some people will just bitch and scream a lot.
Team Assault will need a patch to address a few 'oops' factors. So be it, I am not holding it against the developers.
The manual will happen. The demo likely will happen. The bitching will happen too

(wargamers bitch for the sake of bitching).
The only thing I think the developers can do wrong, is fail to exploit the revolution in gaming device choices. Only an idiot thinks wargaming must stay on the PC. Fortunately the developers chose to be with Slitherine, and thus you have wargaming's best choice of publishers.
There is no anti piracy method to piss you off, and you can find games from Slitherine to run on PC, DS, PSP, and tablets (both iPad and others).
Life has prevented me from playing my day 1 purchase. Oh well sucks to be me

I have not regretted the purchase.
I do sometimes regret being a wargamer though

Some of our crowd can be really embarassing.
