I'm assuming every battlemap you might need is not included as there are only 2 maps included - however - is every token you would need to run the included encounters, well, included?
There's only one sheet of tokens, so no. And one sheet of Dungeon Tiles.
But ... if you add the Monster Vault and the Master Set of Dungeon Tiles, yes, you have everything you need to run the game. This is why we needed Essentials. Sets like this can assume you have certain products and build off them. It's got some custom tiles, like a neat Bahamut emblem and some tiles of creatures frozen in ice.
