The original release seemed pretty flat to me, compared to Civ 4 with its two expansions, but this does look to make it a little more interesting. Espionage looks potentially dull, but religion looks like it could add some much needed variety, and the city-states may be a little less boring.

June 19th and 22nd, for different regions.

It's listed as $30 in the US though, now that I look, definitely not worth that from what I've seen...

Civ 5 worth getting?

Yes! There are plently of places to get it for cheap too.

No Leonard Nimoy was a bit of a set-back for my money.

Have they fixed Multiplayer yet?

When I last tried it, there was no 'save game' for multiplayer (which is obviously fuckin un-usable unless you leave your PC on for days at a time between sessions.)

Seriously, who the fuck is gonna play through a whole session of Civ in a single sitting!

It's listed as $30 in the US though, now that I look, definitely not worth that from what I've seen...

which means it's gonna be $50AUD at least I imagine... Civ 5 is still listed @ $69.99 for std, or 89.99 for GOTY on Steam currently.
I purchased my copy of the game for $40 at launch (I don't recall which online retailer, but one of em...)

I've gone back to playing Civ IV.. Civ V was meh
