Didn't you watch Another, tho?
For me, it's elements and aesthetics. You give me video, I'll pretty easily be able to tell if I like it. A detailed feature-list can be fine sometimes, too, but these days I can pretty easily tell if I'm going to like something to some degree by seeing it in action. Mostly thanks to the indie revolution- which reminds me, started The Magic Circle yesterday. Really clever game right there, reminds me a lot of that one DS game where you could reshape the world, enemies, and weapons with a book- the name escapes me, though.
But yeah, waiting to play Pirate's Curse until I can get Risky's Revenge on DS and beat the original, since it has a consistent story. Fun series, right there.
