Oc is not as bad as people make it out to be. If you are starving for some good old D&D you can probably stomach it and even enjoy it a little(I know I did).
Motb has been great so far(playing it through right now). Can't comment on SoZ, but I like the idea of it. I don't see anyone commenting on MoW at all, so it must be quite unremarkable or something.
Mysteries of Westgate is almost okay. I wanted to like it, being an urban adventure with many shady elements, and I guess it was kind of worth playing, but it's like if they have good things designed, but then it's reviewed by a "dumbing-down department" or something like that. Looks like it was conceived as a town to explore and adventure into, but in the end you're always told where to go. Party members look interesting but in the end are the same as always, etc.
