I really, really love how Sacred Gold handles inventory.
Yes, down to the fact that each potion takes its own discrete tile. In Sacred 2, they made potions stackable, but somehow that wasn't as awesome.
Sacred Gold's system gives me the feeling that I'm actually packing stuff into my character's bags. ~_o God knows why, but that makes me a happy, tickled nugget.
I think it's a throwback from my days of playing tons of Tetris. Tetris + loot = win!
