I know it is the game play that counts...and having lower end graphics means I can play it... but surely a game that is done in turns could have better graphics then one that is playing in real time like a flight sim?
I think the graphics are fine and that their idea of focusing on gameplay rather than graphics really paid off and there are some mods out there that can really enhance the gameplay for you. The next version is going to have better graphics but again I hope that they gameplay and especially the AI(it's not great at attacking once you get the hang of the game but it still can put up a good fight) is improved.

Mind you, I must admit I was impressed when I saw a Sherman I had incautiously ordered over a ridge spot a concealed Tiger, turn to present the minimum frontal profile to it, and reverse back over the ridge like a bat out of hell, all under AI control (had it carried on obeying my orders it would have been knocked out in seconds) . I think the AI is pretty good, as these things go.
Lucky you, mine never make it back over the ridge lol. BTW, if you have FOW on full or extreme, that "Tiger" might be a regular PzIV!
