But I realize for some group, the classics of the 90s are something that can never be replicated and any attempt to is obviously a greedy cash grab
I have a different view. The "classics" we speak about here (BG and following) were based on pen&paper systems that were heavily developed and played for years.
Not just the expansive ruleset they had, but also the settings had excellent designers working on those for many, many years, and tons of group of players pouring over those.
BG isn't simply AD&D, it's Forgotten Realms. And Torment wasn't original material, it was Planescape, and Planescape was genius level before someone even thought of making a computer game out of it.
This new Torment tried to do the same by going for a pen & paper ruleset first, but it has not the same depth of the classics and those who played it confirmed the large majority of the actual ruleset has been cut from the computer Torment we got.
These new CRPGs we're getting are "orphans" of the original material the old ones were based on. They greatly suffer from it.
That's why Temple of Elemental Evil was good. It wasn't new material. The picked an old module and converted it.
But trying to jumpstart a brand new setting will never achieve the depth of a setting that has been actively and intensely developed for many years.
