As we all know, Square-Enix is a powerful player when it comes to the RPG realm. In fact, think about it, how many other good tradition RPGs have you seen recently on the Playstation platform, none really. In the past few years only Bandai, Konmai, and Midway have tried to, with Dot Hack, Suidoken and Shadow Hearts series. Yet both Midway and Konmai have avoided mainstream games, Shadow Hearts is a intensely Gothic game, and Suidoken is a cult game. So that leaves only poor Bandai, they tried advertise intensively while the made their games, or do I need to remind you? The Dot Hack series consists of 8 video games, 3 television series, 2 movies, 4 book series, 2 independent books, a trading card game, and a comic strip. And the highest rating any of the games got was a ... 7. Other gaming publishers went with the sub-genre of strategy RPGs, yet even there Square-Enix has already surpassed them all with Final Fantasy Tactics, making their only blessing was Square-Enix's decision not to remake it on the PS2.
Sony, realizing this was going on, goes back and revived their own RPG series, Wild Arms. (Yes, I do realize that this happened about a year and a half ago, but it's still an ongoing problem.) Hoping that their fan base, and loads of money could develop a game that would give Square-Enix competition, but well they failed. They were apparently rusty and could not develop a competitive game.
Now, many of you may wonder, who cares if Square-Enix is dominate, they make awesome games. Well, I do agree with you, just take a look a the games I own and see how more are Square-Enix titles, but remember Unlimited Saga, or Radita Stories. There is a reason why we have anti-trust laws, in a competitive market the firms tries to obtain more sales through lower prices or better goods, so the consumer (you) wins.
