There is no doubt regarding the state of the game they released it in and I do not think anyone can deny what a low blow it was to all the supporters of the Total War franchise. It was such a disaster that even today, after 4 patches, there is still a lot of work to be done, but to deny the significant steps in the right direction is not really objective, is it? There are a lot of indicators that CA does seem to listen to the community and as always - actions speak louder than words. The proof for my statement is probably one of the biggest design choice reversals so far - the removal of victory points where they do not belong. There have also been numerous tweaks, adjustments and fixes where it was most needed according to the time dedicated for such things. I really do not need to go through all the patch notes - it is all documented.
Is it a direct evidence of how rushed the game was? Absolutely, but what makes you think that CA will leave it as it is? Especially with the apparent DLC whoring plans, that will probably be the most extensive ones in any TW game to date. Fortunately, they have put themselves in a situation where they must regain the trust of their fans in order to issue future DLCs. Let's be honest, I don't think any reasonable individual would shell out money for DLC until the game meets the demands of the consumer. Simply put, CA has no choice but to listen to the community and patch Rome II until it pleases the scammed consumers. If CA has the smallest grain of respect for their beloved Total War franchise and its supporters, they will live up to their promises and never cease to patch the game until the issues have been cleared and cut content has been added back in. I am hopeful that CA truly cares, but I am convinced that SEGA does not. I suppose the only thing we can do is wait it out and see how it plays out, or ask for a refund? The choice is ultimately ours, but in the process of making it, no one should be making definitive conclusions until it is all over. Other than that - it is all bold presumptions about the future that hold no ground if you logically examine the situation.
As for the still remaining issues - we do know how severe they are, but with the obvious rushed release, do we really know how long it will take to address them? Take the AI for example... The community just does not know what to make of it - is it truly that bad or is it bugged beyond belief? I guess we will find out in the future. I choose to believe the latter, simply because I believe that CA is not an assembly of idiots to hype it to such a degree only to spit in our face and take our money. It does not make sense for any kind of a business, especially one involved in the gaming industry and having its success rooted in one massive franchise. What do they gain in the long run? We all know that Total War games are not record breakers when it comes to day 1 sales, the majority of the profit from these games has always been in the long run. Rome II's reputation has been absolutely ravaged and it is CA's biggest title yet. In my opinion, it is out of the question whether or not it is going to be abandoned. Again, my optimism comes into play, but the circumstances are such that they will be the ultimate test for CA, bigger than the Empire fiasco.
When it comes to the actual game - the statement that it needs to be overhauled or redesigned is incredibly far fetched and exaggerated and I will explain why. The core of the game is really solid, but it will take a working AI to compliment it and make it shine. As it is now, the whole game just crumbles under the weight of the bugs, glitches, horrible optimization, bugged AI, poorly thought out features etc. Then we have stupid

like soldiers burning down gates and instant transport fleets. But is there anything that can't be addressed through a patch? Let me return to my original statement - if Rome II works properly with all the issued cleared and some needed adjustments, what is holding it back from becoming the best in the series? The only major feature I see missing from the campaign is the family tree, which hopefully will not remain ignored. Apart from the campaign, there are missing troop abilities from previous titles, but CA have already started bringing pack some of those (loose formation in latest patch). Then we have the multiplayer component, which is obviously barebones due to inexcusable DLC plans. It is not that the core game is flawed, but that too much content has been cut for DLC.
Finally, for the possible scenarios that may play out, it is up to CA and SEGA. The best thing we can do is keep up the pressure and refuse to buy ANY DLC until we get what we were promised.
