Yeah, I don't think it had much of an impact either apart from Triple Triad. It was so awesome, that they decided to make a really troutty version of it called Tetra Master. And then Sphere Break, which was more fun than Tetra Master, but still no worthwhile rewards compared to Triple Triad. I really loved the Junction system, partly because it was so much fun to exploit, and I thought monsters leveling up with you was a pretty neat idea.
