I have played a GREAT many wargames over the years, some are more fun than others, some are more detailed than others
Few ever get the fun factor this high
And no amount of detail will cover for a low fun rating :)

The interface is very basic ie not complicated
Normally you can only get this much fun on tablet games, so I'm having fun playing it on my desktop because their is life after hand held devices eh

Eventually you get tired of anything, and frankly there is a limit to how often you can wargame Stalingrad/Bulge/Marines/Desert designs
I'd compare this with the old board game Blitzkrieg from Avalon Hill
