Meh, the only game I want is Dust out of this bundle. I don't want the other games and sadly won't drop a dollar on it for one game I want and 3 I don't want. Plus I'm already blowing money on Strider (not really blowing, I really want it) and I bought the Sid Meier pack last time around (and paid $15, only because it was cheaper to get the Brave New World expansion that way then buying it out right (yes I had already bought Civ 5 and the Gods and Kings expansion well before).
I don't honestly know how long an actual scenario take to play but playing just a random set-up game with 12 other AI civs takes roughly 5-6 hours to play (shorter then that in BNW with the new Culture Victory (I can usually win in 3 hours and before the 1900's, however this is playing a mod Civ called the Ancients that are OP)) if you know what your doing. The first game I played took 9 hours total to beat as I had to learn all the new crap they added (I never played 4, reason why I bought the pack was so I could get it and play it) since Civ 3. A great game and it's not like you have to invest more then your willing to in a match (you can save). Definitely not for those who don't have the patience for long-term strategy games or politics.
