I love that they cut out many small elements which were just annoying.
Like this one: You practically had to have a unit in every city you founded. Just make it so that you don't have to make that anymore.
You don't have to road every tile to infinity anymore. Wow is that good, it makes no sense anymore and saves me that unintelligent hassle.
The stacks of doom are gone. Units now don't feel that replaceable anymore. It is tactical albeit the AI is bad at it atm, I'll give you that.
I love the new maps, they immerse me much more. I like the worlds, they don't feel as small as the Civ4 maps anymore. I am a huge map fan, and huge maps in Civ 5 play so different, it's a whole new feeling. It's also not pure LANDGRAB anymore as it often was for me on huge maps in Civ4.
I am ready to go to war for another strategic resource, or a luxury resource. I feel I need them more. I now have to think about if I should build a city or not, and where. Before, I'd only think about "where can I find new room for a city that is somehow passable".
It does not feel like civ 4 bts anymore, which is a good thing, because I plan to play that occasionally from time to time. Civ 4 feels more like an optimization robot game (all of these exact numbers everywhere), which I also like, similar to games like moo2 (though moo2 was really easy, at least for me, but sooo customizable (similar feeling to Alpha Centauri which was also sandbox easy, but so fun) - civ 4 gives you much choice instead, also good). A lot of Civ 4 is good micro management. With that, you can get away with so much. And some of that was cut out in 5. Thankfully not to the extent of moo2=>moo3.
Compared to civ 3.. come on, for me, every civ release was better than civ 3.
Call to Power.. couldn't really immerse me. I don't know why, though it had great concepts. It stayed too buggy for my taste though as well..
For sure, the AI is much better than in civ 1 or civ 2. Civ 1 Deity could be beaten easily by building nearly exclusively chariots. In Civ 2, you could win Deity so consistently and so easily, it was not even funny anymore - even by

tactics like "buy your new city" / fundamentalism. These games for me could be played to death easily because they were just too simple, and there wasn't enough to try out.
In Civ 5, there is a "roleplay" strategy waiting for each of the Leaders because their specialties are even more definite than in Civ 4.
Civ 5 has adopted some new ideas in diplomacy, like a casus belli and a true to the word concept, similar to great games like EU3.
What makes me sad is that this game is unbelievably bug ridden up until now. I started 5 games until now. Each of these tries ended with a bug making the game impossible to continue, or just destroying the atmosphere it had created by one or two nasty bugs or unintended consequences of game elements.
(City State X, though eliminated since 1000 years, is now my ally, because I had war with Civilization Y, which doesn't exist anymore either but whose capital is a puppet of Civilization Z which declared war on me, because I attacked City State W, which once was pledged to be protected by Civilization Z. / the 1300 BC rifleman eliminates half a continent / you have to build in your puppet state! you cannot? bad player! you may not continue turns!).
Tough love. I'm going to hibernate some days at my girlfriend's and wait till a patch will come out. I only played 15 hours since EU release, must be a bad game
