If this is all about the game, then the first time in need is the visual of the fighting game you are planning, why visual? Because a gamer is more likely to see the visual first to play the game. In addition, the development of the game should also be good, such as the Android game C.A.T.S, the game is simple, but the players will continue to seek perfection with their up grade player. Your idea is very good, but I think it will be very difficult to implemented
When we discussed this idea within our team we kind of think that it is more about the community and getting social than just the graphics. Of course we might be wrong. And you may say the games with web based interface might be outdated. However we think that the main concept is not only about graphical part but more about the rules insides the worlds controlled by community representatives, economical motivation of players and tournaments where you win or loose depending on your skill sets and previous fight experience. The fight process should value your previous experience but at the same time leave some tactics to bit you even if your skill are better.
I'm not saying out to date, but I also recommend that the visual games that you will make to be more attractive, this aims to make gamers more enjoy in playing the game. Because if it's about a game, it's also about hobbies and fun too. And visually here has a role that gamers enjoy more, unless you develop games such as chess or other board games. Of course the visual is not really in need because the game board focuses on strategy
