1. Great artists can automatically convert another civ's city to your side. That's way OP.
Are you playing against other humans or just against the AI? In my experience the AI will almost never use a GA to flip a city. They mostly just settle them. From what I've observed they only go for the flip if they already have a GA settled in every city.
The GA flip can seem overpowered, but there are lots of ways to defend against them. Most good players focus primarily on offensive armies rather than defensive. If your city gets flipped, just take it back. I played a game a couple of weeks ago in which the same city (former AI capital) got flipped twice by my human opponent. He should have learned after the first flip that he wasn't doing me much harm.
2. In Civilization 4 you can improve your production by improving tiles and such. In this game if you have a slow production there isn't much you can do - making a production boosting structure would take a huge amount of time.
Yeah, CivRev doesn't do tile improvements. As far as production improvements, you've got workshops, factories and iron mines. Getting to the 200 production achievement isn't that hard with a good city site. 200 production is kind of absurd, if you've never had it. You can completely run out of things to build in just a few turns.
The other thing is that you can rush buy everything from the start in CivRev, which can really speed things up.
3. There has hardly been a single game in which each AI would not attack me one time or another. Why is GANDHI attacking me???
The AI don't really have personalities other than certain tendencies granted by their governments. Gandhi is attacking you because he has Fundamentalism and can switch to it at will. That makes India the most aggressive AI civ which yes is ironic. The AI isn't really a very strong feature in this game. I find it much more satisfying to play against human players.
4. Yep, yet due to the lack of diplomacy standings, the AIs don't really like or dislike eachother in game, nor can they have standings with you. You can trade a lot with an AI and they won't feel any better or worse about you. You can bribe a civ into attacking an AI and that AI won't have a lower standing with you.
Yeah see above. There's no standing really at all. The AI won't remember that you were at war mere moments ago. Again, human opponents are more interesting.
5&6. Lack of open borders or other agreements prevents you from crossing an ai civ that has settled a chokepoint without declaring war.
This is more of an advantage to a human player than to the AI. You can use your early game warriors to completely block the AI and they will rarely if ever declare war before the ADs. So you can sometimes keep the AI down to 1-2 cities basically forever for just the cost of a couple of warriors. If you want to cross AI territory, just do it and then ask for peace. You'll usually get it.
7. Which is a horrible, horrible game mechanic. A veteran spearman who's good at engineering and guerilla warfare still should not stand any more than a 0.001% chance against my grandma in a tank.
Well, it just crunches numbers. Pikemen (I assume you mean since there are no spearmen in CivRev) have 3 defense. Tanks have 10 offense. Seems like a wide divide but 3 will beat 10 sometimes. Whatever, if you can accept Abraham Lincoln planting the flag to found Washington in 4000 BC, this should be easy to swallow.
8. Yet in almost any plausible situation a tank army would slaughter a spearman army in a fight.
True in CivRev as well. I think I've seen pikes beat tanks only once and that was a walled city with a million upgrades.
9. Yet why can't they have the huge variety of choices available in Civilization 4 in Civilization Revolution? I know that they want to streamline things, but that's to make it more user friendly to newcomers. Having more diverse and interesting scenarios, diplomacy options, etc. does NOT make it more tedious or less fun to play. In contrast, having such options greatly increases the fun and replay value. It's not like it's for hardware problems; a PS3 or XBOX360 can easily run Civilization Revolution.
Well there are bugs in the game. More stuff is always cool, I quite agree, but there are some existing issues. More stuff might've meant more bugs. This was the franchise's first foray into console gaming. I think it was a pretty good effort, but like I said, I'm really just about the online play. If you want basically Civ IV then you're better off playing Civ IV (the same can be said for Civ V I think).
10. Tech tree is messed up. I got to the modern era without having discovered how to harvest wheat. The bonuses and effects of the tech often times do not match the tech itself, and some techs simply have no effects at all.
That must have been a very slow game. CivRev lets you automatically backfill early techs if you don't research them in the early game. For example, Irrigation is a 50 beaker tech. If you don't get it and then later in the game you complete a different tech at 51+ beakers per turn, you'll get Irrigation for free. So you must have made it to modern without ever doing better than 50 beakers per turn. Not sure how you managed that. Anyway, this shouldn't normally happen. The mechanic is there to give you the early techs for free. As far as I know, this is the only game in the series that does that.
Printing Press is (IIRC) the only tech that does nothing at all other than give you +1 culture per city if you are first to research it, which I agree is kind of stupid. If you aren't there first, the tech is basically ignorable as it isn't on the tech path to Space Flight and there are no other victory conditions that rely on the upper end of the tech tree.
11. The separate attack/defense stats are poorly thought out. In an open plains, given the scale of the game, if a group of legionaries are charging at a group of knights from one "tile" away, the knights are not on the defensive tactically, because they have several kilometers to sally out.
This is nothing new. In Civ V archers can shoot farther than infantry. If I'm 100 meters from a guy who wants to kill me, please let him have a bow and arrow, not an assault rifle, but that's how it works in Civ. Realism is constantly sacrificed to make the game more playable.
