I played Civ II a long time ago when in the years right after it came out, and was engrossed by it. I haven't played much of anything in the years since. I still play the old Civ II once or twice a month, but I was curious about all the following versions and have wanted to give them a try for a while now, but wasn't sure which one is the 'best' - if there is such a thing. Also, I'm wondering how different the newer versions are from the one I'm familiar with - and whether there would be a steep learning curve (as I would prefer not to spend too much time just to figure out how everything works). I'd appreciate any input anyone would have on this.
