You're right about their uniformity. It's starting to look like the same tourney over and over again, just at a different place. Matchroom does seem to have a road map though with their team events, WC of Pool, and the Premiere League. The only thing they are missing is star power. They figured it out on the snooker side long ago, or maybe they were just lucky to have so many characters that even non-snooker players took an interest. The characters in the pool story haven't been developed yet, maybe with the exception of Earl but he's obviously done competing at this level. Even Shaw seems to be losing interest and he's quite the character. Filler should play the villian. Too many Cinderellas to name. The background stories on many of these players would be amazing to hear.
Guess we're just talking about the game though, and there you're right -- variety is good, even if it's just to distinguish the different events from each other.
