It's definitely true that most popular does not always equal the best, but it's part of the brain storming process. You can take something that's not the best and end up making something way better out of it. Either way though, it's a good move.
And yes, some way for players to actually play the card game would be awesome. My one problem with Triple Triad is awesome as it is, there's a finite combination of cards you can have, which is why Tetra Master and its incredibly ambiguous rule set was the one they added to POL.
