Doors. Resident Evil fans know only too well what a door means. It means a few seconds to sweat blood, mop brows and generally panic about what's on the other side, because apart from a few staircases in the RE remake, virtually every door in a Resident Evil game since the days of the Saturn has incurred a loading screen.
Thankfully, Famitsu reports that things will change with Resident Evil Online. According to the Japanese games mag, players will be able to blow doors open (presumably with guns, or explosives, and not just their rank breath), and zombies will be able to knock them down in pursuit of players.
We should be able to see this in action at E3, where we hope to actually play RE Online.
