It's not a full game, itself, though. I could go get a PS2 and Dark Cloud for a more complete game with a somewhat similar theme.
The game itself, if I understand correctly, is a sim-type game along the lines of Sim City. I've played sim games before, most notably, Roller Coaster Tycoon. There's a lot to do, several scenarios, and a near-infinite number of ways to build a park. Essentially, I feel like the actual gameplay that this game consists of is about equal to one individual scenario of Roller Coaster Tycoon, only it's probably not in real-time, and there's less available options. However, this game is obviously prettier, I'll give it that. Roller Coaster Tycoon ran for $30 when it came out, IIRC, and it, as far as I can tell has several times the content available than what this game could have if you bought everything. Yes, you can factor in inflation and all that jazz, but we've learned that inflation and technology don't go hand-in-hand.
On top of that, the character, building, and world models have probably already been developed, at least to some extent, for the Wii FF:CC that's on the way (supposedly, since we haven't heard about it in about a year). My point is, this game was likely very cheap for SE to make. The gameplay, as far as I've read, seems to be very immature and devoid of any decent level of interaction. The biggest issue for me, is that I don't feel that what SE is offering for a $39 whole package is even worth the "trial" $15. If SE would say that the game is an investment, and that what happens here can benefit other games, maybe I'd go for it. I like real gimmicks. They haven't, though, and I'm seriously debating whether this game would be worth my money, something I rarely do, rather, I worry about titles being worth my time.
I don't know. Maybe there's more there to it. I certainly haven't followed every little piece about it. It just seems to me that the "trial" UncleBob suggests isn't even much as a trial, I see more gameplay available for free demos than I expect from this game.
We'll just have to see.
