Oh, right, I didn't answer your question from a few pages ago: I have not tried some of the other games mentioned in this thread. I certainly might enjoy them. I enjoy lots of games that aren't even RPGs. And just as I like puzzles on their own, but don't really like solving them in D&D, it's possible that I would enjoy the mechanics you describe in other contexts. I wouldn't be averse to playing those games (except that already there are so many games, so little time).
What I do know is:
- Mechanics which blur that line in D&D bother me. E.g., Inspiring Leader, and even a bunch of Bard abilities, which bug me even though that can easily be written off as magic (or 'maaaaaagic' as one might say more derisively.)
- I don't like it when my group decides that we should all pretend to not know something. (Which reminds me: I have used the term 'mind control' in this thread, but in the literal sense when I described a recent scenario where a monster mind controlled a member of the party.)
- I recoil in horror every time a poster describes how they, as DM, would be the arbiter of what "makes sense" for a PC.
