In the DOS games, the many mostly-empty lootable containers were meant to interact with the Lucky Charm and Telekinesis skills. What are they meant to do in BG3?
What makes you believe that those are not planned for BG-3 ?
What makes you believe they are? How do you imagine these skills would be implemented? I'm not fluent in the rules, so feel free to correct me, but I don't believe PHB has any spells, feats, or class features equivalent to either Lucky Charm or Telekinesis, excepting the level 5 spell with the same name. And even with Telekinesis spell, it only becomes available at character level 9. The level cap, whether the initial 10 or the current 12/14 (as speculated), makes it safe to assume we'll get access to level 5 spells in the latter half of the game, if not the final act. Either way, there is absolutely no chance we'll be able to hit level 9 in act 1. With that in mind, it makes no sense to design maps around the use of a single spell you have no way of learning at this stage of the game, among other issues.
Another thing. I have no games development experience, so again correct me if I'm wrong, but it seems to me that if Larian planned to graft some systems from DOS onto BG3 wholesale, they'd have done so in the beginning. It's the same engine, so most of the functionality is already written and in working order, no? That is what happened with surfaces and surface interactions, at least. I see no reason to believe they could have included that from the beginning, but not Telekinesis and Lucky Charm, if they intended to include both.
