I too am curious about Monte's new RPG. The description given on the website sounds less than promising, but Monte has put out good stuff before. There is little I could glean from Monte's corporate-grade shilling-speak.
As for the video game, I'm doubtful. From the looks of it, he's just cashing in on Torment's good name and tacking its surface-level aesthetic on a setting that has absolutely nothing to do with Planescape. It'll have factions and it'll have a ramshackle city, but it won't have the heart of Torment: the examination of belief, morality, and perspective in a world that is literally built around those things. If they advertised it as anything else instead of "inspired by Torment," I would be more excited.
To the question of which sci-fi fantasy system is my favourite: I haven't played many, but I enjoy Rogue Trader quite a lot. Eclipse Phase is also fun, although it is a pain to set up.
