This isn't that surprising - the game has failed to gather hype thus far, why should it suddenly become popular overnight? I think there is something about this game that clearly puts off the "hardcore" gamer. It's possible that because it looks so much like an action game, people are judging its graphics against other action games rather than RPGs. (Although personally, I think it looks pretty good. Certainly better than I expected.) It's also possible that the "spy movie" setting isn't as immediately grabbing as a fantasy or sci-fi setting would be. (Watching videos of Mass Effect are immediately distinctive because of the ways certain aliens, ships, etc., look. Similarly, Final Fantasy has a very specific J-Pop-ish look. Alpha Protocol, being set on present-day Earth, looks...like present day Earth.) Whatever the reason, it's probably too late to fix at this point.
Oh well! I'm still just as excited to play this game. It seems destined to become something that is loved a lot by a very specific niche. I just want to play it already!
