Dragon Age is from Bioware and from the looks of it, seems like next Neverwinter Nights, thus pausable (=turnbased) high quality WRPG. It's comming on PC aswell as 2 other platforms.
Demon's Soul is more of survival-horror kind of action JRPG with great difficulty (=not for casuals) which also breeds great satisfaction if mastered. It's PS3 exclusive.
PS3 fanboys will say go for Demon's Soul, XBox fanboys will point you at Dragon Age. But both games are quiete different stylewise, so pick up what feels more natural to your taste. Also piracy shouldn't be suggested as a way to obtain games. Yet the fact that PS3 is the only unbreached system can tell you something while asking for advice on this matter.
MY HYPE LIST: 1) Gran Turismo 5; 2) Civilization V; 3) Starcraft II; 4) The Last Guardian; 5) Metal Gear Solid: Rising
