This simulated 'what if' scenario is another superb game from a developer who has achieved an excellent balance of playability and authenticity. I imagine many strategy fans who are used to flashy graphics and pinch and zoom interfaces will but be put with the basic 2d interface on the screenshots and get no further. However, what is important in a game? If you judge playability and authenticity above fancy graphics and modern interfaces, then look no further. Furthermore, the rest of these developers apps use the same engine, and broadly the same system bar a few scenario specific differences here and there, so you can get another app and be up and running immediately. Definitely recommended for serious warmers.

I have played many of Joni's games. They take me back to long days with the Avalon Hill classics. First time I tried Sea Lion I thought it was close to impossible. Let me just say that you are pretty likely to hit some tight supply situations and if you are not managing the naval side well, you are in for some pain! This time around I got it right and was able to manage a successful campaign. Thanks, Joni. I bought a better Android device just to play your games. Wish some of the $ went your way.

Great addition Challenging scenario for veterans of the Conflict Series. Based on a hypothetical invasion of the UK, it introduces new elements like supply ships, destroyers, amphibious landings, and looting for supplies. Offers great replay value to explore different landing zones, etc. Probably a bit complex for first time players of the Conflict Series. I'd recommend starting with the Stalingrad or Eastern Front games first.

Again, another game I will have to delete because I feel the balance is just plain wrong and frustrating. Not up to his best work, and I really do not like the direction he is taking. I will keep an eye on what he continues to produce, but I guess he just cannot please everyone all the time!

Where is the tutorial. Anything to explain how to play. I am a lifelong war gamer, but I still need some kind of tutorial. If you don't want me to delete and use my big mouth, then send me a tutorial.
