If I go into a weapon store to buy a new sword, wouldn't you think it would be better to actually have to grab the item from the shelf and place on the counter. The NPC would say how much it costs and you'd drop the required money on the counter or in his hand. Or maybe just clicking "purchase item" on a dialogue window that pops up.
Now that games like Oblivion and Skyrim have physics in their engine I don't see how this couldn't be done. They already have items on display in cabinets and on benches in Oblivion. Wouldn't it be awesome if they were more than just decoration, and instead would be what the store is actually selling.
What do you guys think?
