Aside from chests being similar and too big, whilst not containing much really. Does anyone else remember the sheer amount of hidden areas in the original BG1 & 2 maps? From tiny, missable rocks with hidden rings, or gems, to walls, or hidden doors, or even cracks in dungeon walls?
There was a good amount to discover behind a painting or two, or a stuffed head on a wall, statue base. Larian probably has plans for all that sort of stuff, but I agree, make the chests make sense and put them in places where someone might actually dig and bury something for real.
