Ever since playing this with my cousins and brother back in the 1960s, I've always thought this the greatest'Waddingtons' board game of them all. But of course it's not made by Waddingtons any more.
Over the decades the game has been updated, to persuade me to buy another copy. In the 1980s, the Parker Brothers variant introduced Objective cards whose content you only disclosed at the moment you were claiming a win. For this new version, the idea of objectives have been retained, but all players can see them, and you only receive the objective when you've actually achieved it. We need not bother with all the film tie-in versions: Narnia, Lord of the Rings, Transformers, Star Wars etc.
I like it. As other players have observed, the game is over more quickly than previous versions, although set-up can take a long time, particularly the introductory game. My biggest gripe is with the arrow pieces which are not an improvement over the plastic triangles, blocks and beads in earlier variants. I can see that the arrow metaphor works well as an idea, but in practice they're a bit of a bugger to pick up.
The game retains the world map of the original, along with the same continental values -- which means that North America still has an unnatural advantage, and Asia is rarely captured until close to the end of the game. However the game does travel in different directions compared to the original version where world conquest was the only objective. In particular, you need to protect your capital. Hanging on to this is even more important than blockading all the entry points to your continent.
