They're not going to take 100% of the community's advice, and they are right not to do so. You don't make games "by popular demand", it does not work. For one thing, the community isn't monolithic in its demands. For another, if I was a game designer, I would not want to just make the game random people ask me, I would want to make MY game. And if CKII had come out with coalitions and SRs, I would not be here complaining,I would just stop playing because the vision doesn't suit me (pretty much what happened with EUIV for me).
But I completely agree they should have a long look at some of the community has proposed instead of the recent changes. I don't mind a game designer that has a different vision than mine, but I mind a lot when the spirit of a game I am seriously involved in gets so twisted so late in its inception.
I keep hearing the current dev team is new to CKII: for the life of me, I don't understand how they cannot get that they are not supposed to rewrite the game at this stage. They say the old alliance system was too easily gamed: by who?? When?? How can they change something so fundamental so drastically, when clearly they do not have a clue what their changes entail? And what in the world make them think that SRs and coalitions, 2 mechanics that have never been particularly adored in EUIV, are ok to put anywhere else? Talk about wearing blinders...
I don't get these devs, but the one assumption I think I can safely make is that they have very little understanding of the work done by those who preceded them. Except when it comes to Aquitaine and Flanders, then all of the sudden full continuity is assured... Yeah, I feel we lost big time.
On one hand, is not a big deal: we have 2.4.5, an ok final version of CKII. On the other, it means none of the outstanding issues will ever get solved. But then, to be honest, CKII often felt as the game that's almost there, but never quite.
