ok... so now I know the both games because I was playing these days civ4 with beyond the sword , and civ5 gods & kings before that about 5 games... both games I was playing in ''prince'' dificulty that is like normal I like that because the AI don't have advantage and you neither... for a new person that I have tried first civ5 g&k and after civ4bts I can say that:
1. the ''tech tree'' - in both games is a little different but in the same way without major changes or differences is in the same sistem... so Is a draw... I give a point to both games... in civ5g&k I like because it needs much time to achive in ''standard'' mode for both games
2. the ''social policies'' and the ''civics'' - sorry but I like more how are made ''SP'' in civ5g&k ... without doubth is more interestring and is more rewarding with more things to chose is a evolution in good way of ''civics''... in civ4 they don't give an importance to this... a point to Gods & Kings and can optain of a reward with cultural points, so beautifull
3. the ''religion'' and ''espionage'' - is a good addition to civ4 without doubth, but in civ5 g&k relligion is more upgrated give a great importance to the game giving great ways to spread religion, inquisition, and make a great walk in the civilizations history... a point to Gods & Kings... espionage is in much ways the same but with addition of city states and another options the espionage works very good and it's rewarding and in the same way more risky... a point to gods& kings...
4. the '' special buildings , resources , wonders, special units , leaders '' - so the both games have the same number of resources without much addition to Gods&Kings.. but I like the ''natural wonders'' new thing because it gives a more joy to Gods&Kings.... if u are lucky u have some advantages, like youre positioning with te resources and wonders or stuff.. like in the real life, lucky or unlucky... the special units and the bonuses of the leaders both games have a good point... so Gods& Kings is a little more variated but with just little difference not much improved... civ4 beyond the sword have a plus with the microcorporations thing but who cares... I don't want to take care of Aluminium & CO and ''Herbal .... '' I just thing is not worth, without importance... Gods& Kings another point but with just little difference... but I thing is close to a draw...
5. the ''happines, health , culture,money, growth, expand'' of the cities - this is the big difference in both games... so ... civ 4bts gives a more variation , u need to take care of every city to have a growth, expansion with culture,health and happiness with more variation... in civ5g&k the culture happiness and money is in a ''total of all the civilization'' and affect all of the civilization not just a city because he has a ''lack of....'' but, I give a point to civ4bts because it's a little more complexe in this aspect, though I like more in civ5G&K how the cities expand and all the imperium, the unregular form...
6. the ''fighting system, the square/hexagonal grid, exploring, stack/1upt units,'' - here is the second and the last big difference in both games... I thing the points 5. and this point 6. of my oppinions are the major changes and here comes the preferences of the peoples... is simple in civ5g&k the fighting is changed in a so beautiful way that is giving you spirit of the tactical and strategical combat with the hex/grid with more positions and spaces to cover with the magical 1upt system... is more great evolution than in the civ4 and how great it works... the civ4 players complain this but this is just because they don't used to it and don't want a change in these way... my oppinion is that the fighting in a civ game have an very important role like the second civ5 offers it in such a beautifull way... civ 4 have hexes and gives 8 ways compas moving ,but the 6 hex ways work great... the exploring is more addictive and more ''want to search, want to see'' addicting way thing in civ5g&k, though I like the ''globe zoom out effect'' from civ 4... but in this aspect is a point to civ5g&k...
7. the ''A.I.'' - I have seen a lot of discusion in this aspect in a lot of forums but I, playing the both games, in civ4 I can say the A.I. is a little more challenging in harder difficulty than civ5g&k... and more of civ veterans want the stuff more chalenging, but is just a point of view from each side, though challenging it not means greatest or other things... Gods & Kings have a good A.I. , I was playing 5 games in prince difficulty so It was very ballanced for the each side ... I don't wanna the A.I to have all the advantages to kick my a*s but either I didn't want to have the advantage... so let's be fair and give a draw for both games, just because there are both challenging and both A.I. are ok made, despite all the negative comments I can say the both are great in the A.I aspect...
8. The ''graphics, sound, interface, menus'' - ok... these without a doubth, it wins the last game of the franchise with more beautiful menus with a joy to play it, graphics greatful a lovely to watch and the interface more advanced and in simplistic way without is not ''darker'' like in civ4 like ''closed, claustrophobic'' in civ5g&k is like u are on the top of the world watching in all the opened ways with opened skyes and the clouds are a great adition to the unexplored teritory very great... the sound in both games is great buth love much more the sound in the last game... so a point without doubth to civ5g&k ....
In a final comment to a comparation on both games is not much to compare is just what have we seen and what we enjoy.... from my point of view civ4 is good with all the management of the cities, empire growth , but civ5 g&k taking off the annoying stuff is not a deep like civ4bts but the best experience right now with major changes in some things but without changes in another is CIV5G&K... is made to give a good playing experience and its just make civ4 dated in some ways... once u have played deep civ5g&k u don't want to come back to play civ4, not because isn't good is just because is dated in much ways... so is just my oppinion, and thanx... and... just waiting for another civ5 great expansion ''brave new world''... so much to offer...
