First off I would like to say there is no competition between any of the games they are all amazing and provide the user with a good experience little can be said about Arokai as no one has really played it on line, There aren't as many as you think I mean compared to a shooter MMORPG you got hundreds of them when you only have limited amounts of Animal based games, Impressive title and its branch off games such as Impressive world should not really be counted as separate games as they are all truly the same leaving us with even less games, So if you think about it we don't honestly have that many.
