And, different strokes for different folks. From what I've read it seems clear to me that the RPG/Shooter subgenre is really not your cup of tea, CraigCWB, although I also get the feeling that you never gave those games a fair chance. You are certainly very opinionated when it comes to certain rpg-ish games that many of us here at the watch consider to be great fun. FWIW, I believe Jagged Alliance was well-liked here, too.
As Dhruin mentioned, RPGWatch usually covers RPGs and RPG-likes (hard to define the genre nowadays) as well as the occasional game that might be of interest to our readers for one reason or another. That even includes general gaming news that are only tangentially related, or something else of note or interest from the industry, like an article from gamasutra.
Since our beloved "genre" is in constant flux and considering that Bioshock was sort of expected to have at least some RPGish nuances, a look behind the scenes is definitely interesting, if only to gauge the potential damage overzealous usage of the term RPG can do. To be fair though, if I recall correctly, Bioshock was never actually marketed as an RPG or even a "spiritual successor" to System Shock 2; but it was the fans of SS2 who hoped Bioshock would be similar, which it sadly wasn't.
Anyway, we didn't cover Bioshock 2, so it's not like we are actively trying to "water down the genre" as you put it, but we are relatively open-minded when it comes to potential new material. If it later turns out to be a dud… well, better luck next time.
