Yes, there are a whole bunch of people who feel the same way here. Sometimes, when we discuss these things here, I feel part of "Steadler and Waltdorf" from the Muppets.
I'm glad we still get games like Eschalon. It might not be top-notch, but it is better than nothing. I also think that online distribution offers a new hope for these "niche-games". By avoiding the HUGE costs involved in retail, the need to obtain profit from the sheer number of copies sold, decreases.
Currently, my hope for a big-scale, deep, torough, detailed RPG are set on Dragon Age.
On a side note: I don't dislike games like Diablo or WoW, on the contrary. They're awesome, great games, but fall a bit short in the "RPG" category.
