No. I don't even have the Gods & Kings expansion pack despite it having my favorite civilization which is the Byzantine Empire. I bought Civ 5 pretty much when it came out but I never even finished the first game I started playing in it. I've sadly fallen behind in the series.
High point for me would be Civ 3. That was at a time when I did not have the spare capital I do now to blow on games so only owning a small selection of games, I had beaten them all. But with Civilization and all the different things you could do and encounter in it, I played it a lot along with all the expansions. I loved the Conquests scenarios for Civ 3. Especially the World War 2 Pacific theater.
With Civ 4, it took me awhile to come around to it. It didn't help that the computer I had wasn't the most powerful to run it either. But when I finally got a new computer and started playing it at about the same time the first expansion came out for it, I finally got to understand it more and really liked it. By the time, the second expansion came out for it, I played a couple games but it was at that point my gaming interest was waning and I just fell out of it along with console gaming.
I always thought it ironic that the Wii was meant to increase gaming and bring back lapsed gamers but it almost caused me to give up gaming. But I moved out on my own and suddenly having the TV to myself, I could start watching whatever I wanted and became a real movie fanatic not to mention catching up and watching a whole bunch of different shows. Even now, I still probably watch an average of 20 movies a month but there are times where I need a break from cinema and it probably dips below that. On the TV side, I've definitely slowed down. There's very few shows on the air I watch regularly. About 7 right now. I've lost interest in sports for the most part and don't really watch any games anymore. There's not a lot of TV shows I really feel the need to check out. At this point, Damages, The Wire and potentially Person of Interest are the only shows I might start watching as well.
Still for the past year, I've told myself that if I'm not going to start playing this stuff, then maybe it is time to sell it. So, for the past year, I've started making more of an effort to play through my library. Sometimes I seem to make good progress and sometimes I lapse. I want to see if I can keep with the current systems and chip away from the previous generation a bit. If I can't, then I either need to stop buying or give it up. So, we'll see how I'm doing. If I do give it up, one of the few things I might keep would be Civilization though. With the amount of time that can be spent on it, I'd finally be free to do so again.
