There are two stories here. One is that Microsoft is releasing a compilation of six full Xbox Live Arcade titles on disc, and that you'll be able to get your hands on it here in the UK on September 15th. It should go for Ł24.99, although we've seen it listed at Ł19.99, so hunt around.
(The other, less interesting, story is of a my being on holiday last week, a typo in an email address - euorgamer.net, since you ask - and of new-boy Matt being very busy, which is why you're reading about this a week later than you probably ought to have done.)
Anyway, the six games that make up Xbox Live Arcade Unplugged Volume 1 are Geometry Wars: Retro Evolved, Wik: Fable of Souls, Outpost Kaloki X, Bejeweled 2 Deluxe, Hardwood Backgammon and Texas Hold 'Em. A decent mix. If you downloaded them all individually, it would cost you 4000 Microsoft points, or Ł34.00.
That's not all you get either - as Microsoft's throwing in one month of Xbox Live Gold access, and Xbox Live Arcade demo versions of UNO, Marble Blast Ultra and Feeding Frenzy.
On the whole then, an excellent-sounding pack - probably worth it for Geometry Wars, Wik and Kaloki alone. Although, er, perhaps not, since they'd only set you back 2000 points, or Ł17.00. Look, just make your own mind up, alright? And tell your friends - the ones without Internet, since they're presumably the main target, and won't be able to read this item, or the others like it that you might've read a week ago.
