Well there's a lot of difference in all those games, and they're going to attract different types of players. Just compare Sword Girls with Solforge, for instance.

Just as important if not more than competing with other games is competing for awareness. I've done surveys of what other games people play, and the majority of players know about Magic but are unaware of the other games out there.

So I'm not overly concerned but I have done my research and follow what the other games are doing.
