It's a damn fine port, and is running very well on my original iPad Mini. Bought it 7 minutes after midnight, and 7 hours later I'm wondering how I managed to reach Jan 1915. This war ain't over by Christmas. Very impressed with the interface and game itself.
A few minor points, for the first bugfix patch. In no particular order I noted the following:
* The tutorial box for the counter battery stat still has the placeholder text "advice_counterattack_text".
* The numbers in the management tab, showing number of units for each faction is very broken. It was saying I had 81 Serbian ground troops, only one French etc. Have a screenshot if it would help.
* The tutorial box for city production still has the PC text saying you need to hold down the spacebar, needs changing to say the number is next to the city's name (I believe?).
* Sometimes the map scrolling during the AI turn is bugged out. It can be a little slow to get to the current action, and during one turn it spent the entire time focusing on random areas in the middle of Siberia so I missed all the fighting. The AI turn in general sort of belts through a ton of moves very quickly even when it does work. Would it be possible to have an option to replay it? Slow it down? I take my time on my own moves, a little more time to view the AI turn would suit some of us players.
* You can rename your own units, but not AI units. That's fairly common practice, but have you considered giving a generic name to units ala Panzer Corps? Even just 1st Infantry, 2nd Infantry, 3rd Infantry etc. Just makes long wargames a bit more personal with some form of unit names.
* The combat prognosis window sometimes has a little icon meaning a river is being crossed, so the attacker incur a penalty. I know this thanks to the AAR. The tooltip when you press it says "weather: snow".
* Could you please add a confirmation dialogue to the end turn button? Thing about touchscreens, it's awfully easy to make an accidental tap now and then, and in a long gaming session (did I mention 7 solid hours?

* As a new player I found the tutorial popups very useful, and with the staggered start to the war it eases things in slowly enough to not be intimidating. One part of the UI is inconsistent with the rest though. For just about everything, you have tooltips and a confirmation button. Choose a research item, then a separate button to focus on it etc. The one place this isn't the same is the add/remove labs buttons. I was tapping around on everything, because everything has a tooltip teaching me how to play, but I was able to hit the plus and minus signs repeatedly, not knowing what they did, and basically bankrupting my production points on the first turn due to buying and selling the same lab a few times. Had to reload the autosave, but it really should have the same amount of introduction as the rest of the concepts.
* I would like to be able to see a commander's stats before deploying them. They are in the queue, but until I out them on a unit I can't see what specific bonuses they offer. Knowing that this dude is an assault specialist, but this one has just a modest general attack bonus etc before I deploy them would be preferable.
* Probably not possible, but I kept wishing I could close the bottom info section and just see the map filling the entire screen. In Panzer Corp you could minimise the info panel, and for the AI turn I'd usually have it closed for maximum eye candy. Any chance of doing the same here? Would make a hell of a difference on an iPad Mini screen.
Ehhhh, that list was a bit random. Feeling a little dizzy after playing the game all night. I absolutely love it. Gave you a 5 star iTunes review, and I'm looking forward to playing a lot of this game. Already my first game is taking an interesting turn. I somehow managed to hold onto Belgium so far, the Russians have taken Koenigsberg and Danzig, Serbia is in trouble but clinging on, and General Haig is in the Middle East with fighter support and armoured cars. It's only in this new year that trench warfare is setting in, had a very fluid frontline on the Western Front past Xmas. Magic stuff.
