i agree with joshua
if you feel like the money, the time and patience is worth it then keep at it. i've mentioned this at another post but its really up to us (the naruto community) to try getting more players into the game. Bandai can only do so much to reach out to the community (via advertisements increased prizing etc) and we really need to get people in although it shouldn't be our responsibility. if we don't want the game to die, then we need to spend that extra effort to get people into the game.
i would hate to tell you to drop everything, because after spending hundreds, thousands of dollars on a game then dropping it, i would feel like shiz. so i say, try your best to convince people around your area. give them decks to play, find people who play yugioh because usually they like Naruto too, or anyone who loves the anime (you'll find a better success with them) and help them get into the game. that's the best we can do since Bandai might be not able to push as much as they'd like to due to budgets or their decisions.
