I just don't see it earthling. Cities don't start growing super fast until late game, so your complaint that you won't be able to have a ton of big cities until late game is irrelevant.
The reason no one is addressing your problem is because it's not a problem. So what if it doesn't scale entirely evenly on a different map size. It won't really be noticed in actual games for reasons already stated.
You haven't even been reading what I'm saying in the first part. Again, that's not my complaint at all. Though your premises are shaky again, there's little evidence city growth can't occur fast early game - have a capital and core in the teens or 20s even in middle eras, we've seen basically as much on previews and demos too.
I'm sure part of the reason no one is addressing solutions the problem is because they don't actually understand it, many do not have experience with previous civ games or understood problems there either, but at least the thread will be around when other people show up and complain. This is just like saying "nobody notices that Marathon speed or whatever isn't balanced." Well, fine, some players may not notice or care, but that's not been true for the community, and it won't be true if there are major problems in civ5 either.
Can you really have a serious discussion based on assumptions?
I don't see how this is a valid line of reasoning about anything on the forums at all- if you didn't want to post here, don't. If you want to just go wherever on the forums and post about, I dunno, ice cream then go ahead and try that, but you'll find other people in other threads have outlined topics of discussion in their OPs. But generally it is expected that a serious thread can be detailed by an OP and discussion will stay on topic.
So far the answer appears to be: nobody has a single solid suggestion that playing larger maps with larger empires won't be trouble. So then we have to expect that playing on huge maps will not be feasible the way it was in previous civ games. At least there are possibilities for improvement.
Your objection is to a bonus that really only helps small civs. Actually, you have a lot more to complain about than just a static happiness bonus... there is also social policies that benefit only the capital and the fact that social policy and golden age costs will scale with the number of cities you have (is this confirmed?). The latter, if true, would be a much bigger detriment to large empires than not enjoying the static happiness boost, in my opinion.
Oh, I've discussed elsewhere lots of things that cause problems on huge maps. A thread to discuss everything would get to complicated especially with inexperienced players or false "factoids" gathered from civ5 sources that aren't accurate and don't know what they are talking about. For instance I certainly don't like the ridiculousness that Domination victory has become relating to captals, nor problems we'll face in warfare and so on. But I would have thought if we just proposed ideas/gathered knowledge on happiness somebody would have some ideas to improve things, looks like not.
I appreciate your post though gruther. I am optimistic in that I do expect some of the other things you've listed they will have actually scaled in the game (or who knows, maybe happiness scales some places too, we don't really have technical details on the mechanics. Would have liked to find that out but we don't know yet).
But I think we will see that technology, culture for Social Policies, and so on probably will scale with mapsize, hope all these other folks aren't angry to find that out. It would be nice if they did well with their testing and balancing.
