Actually I meant, why do you think it should be a download title instead of retail? What makes you feel it was low budget? The art style?
The gameplay seems very close to Pikmin, so it's kind of a RTS, but it has life simulation and RPG aspects. You build up your kingdom, take your followers which have different jobs and thus are more or less efficient on the different tasks, like fighting enemies, building structures or digging for treasure. You have boss fights, there's 6 rival kingdoms you have to conquer. The game's few reviews until now all gave 90%+ and stated that it's a great game and it's not a short game.
That's about all I know about this game. I don't know how much it cost to make, but I feel its full price is adequate. Even if it didn't have a huge budget, I'd still think that, because if it's good fun I'm willing to pay that much.
