I haven't brought the game because it was on Steam, I was going to wait a year or two and hope to see it on D2D.
Reading the reviews carefully, including the awesome detailed report by "Sulla"
(
http://www.garath.net/Sullla/Civ5/civ5SP.html ) it looks like Civ IV and expansions were like Ultima VII and expansions, awesome games that made the old diehards happy, but attracted new players to the series. Unfortunately the latest version of Civ is the Ultima IX of the bunch. The spirit of the game was lost somehow.
What really spooked me is how many people are playing at the highest levels and winning the game, after just playing a few games themselves. Even though these are veteran Civ players, it still should be a good while before you have a hoot in Hades of winning on Deity, not at the end of the first week of ownership.
It also was interesting, the comparison between "God Games" and "Board Games". My joy in Civ is not winning, although I play very difficult games to be severely challenged, but I am not a Min-Maxer and enjoy just building a unique empire each time... it never got old.
The lemons HOI3 and Ultima IX also had many dedicated defenders when it came out. Comments defending them were basically familiar:
"You don't get it."
"You didn't see all the flaws of the previous version that this fixes."
"The new combat system is awesome."
"Ultima was too open, I got lost. This is better."
"I'm glad all the do-goody stuff is gone*"
"Give it time"
"Nothing a few patches won't fix, but it's good right now."
"I'm not experiencing any CTDs, so I'm going to imply that you are lying about having a high end gaming machine."
"So what if Stalingrad doesn't have a river in the province? The map is fine. This is nitpicking."
"Diplomacy isn't broken. 1943 Mexico
should be landing troops in Latvia, and I
like that fact that Switzerland declares war on Siam for no reason. That the entire world joins either the Axis or Allies in 1939 is fine. The old system was too numbers-based."
** Nevermind the "Avatar" is supposed to be like a Bodhisvatta with a Sword, the
whole premise of the series.
HOI3 was a bust, and is still 'meh' even with multiple extensive patching and an expansion. BTW, plenty of polls, at least for HOI3, were slightly positive as well, backed by strong comments defending the game as genius. But in the end, HOI3 and Ultima IX went on sale quickly with a rapid price slash. Even a major overhaul from the expansion couldn't save HOI3.
Fortunately, Paradox learned with HOI3 and just put out Victoria2, which had some big bugs/flaws but most were fixed by the second patch just over a month after release.
I don't think that even if Firaxis puts out an amazing patch, they can save this game.
Civ IV on release had some flaws, IMHO, but I still took Vacation days and called in sick to play it, like I did with Civ II and III. I played many hundreds of hours of Civ IV before the first expansion, and probably quite a bit even without serious patching. It had "the spirit", which Civ V seems to be lacking from reports.
YMMV.
