I think the criticisms of ToB are valid, but I still had a lot of fun with it. Even if it was a bit rushed, for me it feels like everything is rapidly escalating towards the big final climatic encounter, so thematically it works. There are also some really fun encounters.

I haven't tried SoD yet. I am not sure if I ever will. I don't need an interim chapter between BG 1 and 2. I have had so long to head canon that period of my Bhaalspawn's life, I don't really want anything that contradicts that.

If Beamdog ever made a completely new, unrelated FR series using the Infinity Engine, I would almost certainly buy that instead. That would actually be pretty cool. I am generally not into retro gaming, but I find that the IE games have aged well. I could play a new one.
