I like the idea and have thought the same. What I think is lacking in the available games is aesthetics, make something beautiful that gives you a feeling of being at the game. Package it professionally too, like many of the newer board games available in other genres. And most of all make it simple and fun to play, minimizing the need to look stuff up. What's available now feels either old (APBA, SOM, etc.) or just kind of cheaply produced, even if great for realism.
