Nothing too different here. Notice how its 2 tiles wider than RPG Maker 2003. One very important difference- the multiple selection of tiles will also work when making events. The entire mass of tiles will be used for collision when the event moves unless you have it ignore collision (recommended).

You will be able to right click eye drop select tiles of huge sizes (off the map), many times the size of RPG Maker 2003. You can right click eye drop tiles to make events too if you want to assemble the event specifically and use that. Handy for epic doors, power lifts, shifting parts of the level, etc. because you would only need 1 event (or 2 for parting doors).
