I have not stopped playing the game because I only occasionally play it since release (about 40 hours total).
This game will defiantly get me entertained for couple of years, especially when the first major mods appear.
I'm still playing Medieval TW2 because of mods... its one of my favorite games.
The only thing that I do dislike is the fact that the MP avatar has been removed as it has been one of the things that I liked about Shogun 2.
..but that is defiantly not stopping me from enjoying the game... those AI-Issues which not have been addressed yet, will be fixed in the future, for sure.
Rome 2 has the biggest scope of any Total War game yet, which means it is most likely very hard for the devs to track down each individual bug.
The constant complains on TWC show me that the gaming community has changed and I can see it on sites like Metacritic as well.
I guess I am part of a dying-out gamer generation who are thankful for certain games that developers are creating. Games like Rome2 are very rare these days.
Its a shame... the fact that Rome2 already supports modding and has a pack manager does get totally disregarded among all those haters.
