I think you know what is best for you as developers. This poll isn't going to change that. It's looking from the answers like there is a right and wrong answer to the poll for you and most users. Don't feel you need 1000 answers. As developers you should take the mod wherever is best for you. Some people won't like it or will be unable to use Better Cities. C'est la vie. Sometimes we have to make choices (example: can't use all cosmetic mods even with BASH.). I think in your hearts the decision has been made, and I wish you the best with it and that it makes new features much easier to add. I didn't vote because I don't feel that my preferences should be part of the nose count. If I had voted...I would have voted selfishly if I voted honestly. I don't want to do that. I hope you get the 1000 go for it responses you are hoping for, but if not, there's a very clear trend already.
I'm still pretty new to the game although your read me would classify me between average and advanced according to the tools and skills you list. I am not yet running Better Cities because I am avoiding big sweeping mods until I have played the game through enough once to explore these areas Bethesda made first. That said, I have intended to use most of the Better Cities when I have done that, and from what I have seen in screeenshots, messages posted about this mod, etc. I admire you greatly. Again, I cannot comment on what I like or dislike about individual parts of your mod in play, because I am a "future user" rather than a current one. It is possible that I can give useful feedback though by expressing some of my concerns as a likely new user since you seem concerned with ease of use for new users. So here goes:
I have a few small immersion and lodging mods which I know do conflict with certain parts of Better Cities. I didn't know about Better Cities when I downloaded them. I know to you guys, it would be silly of me not to just give those up, but I am a roleplayer so I am reluctant to teleport my humble homes elsewhere, and I am also too new to all this to know how to move the houses, or change quests associated with them quite yet. I am currently learning my way around Wrye Bash. I've made plenty of mistakes already, but I'm getting better at it. I should mention there are many many of me. Steam and Impulse have both had incredible deals on the Game of the Year package recently and I am almost certain those deals will get even better in the lead up to Skyrim. It's their last chance to sell it to people like myself who saw the Skyrim promos and were inspired to buy what is available now while we wait.
My concerns:
1. I am not capable yet of making the modifications to the mods I already love, and I am not alone. Some people buying the game now probably aren't interested in modding at all, just downloading mods. You modders are being/about to be invaded by a whole slew of utter newbies because of current promotions. Solution for me: I could download the old modular version if it is still available then, but then I would never be able to upgrade it further. Solution for you: Merge, will make tech support much simpler. You can warn people not to download unless they are comfortable with Wyre Bash but you must know they do anyway. I've barely restrained myself so far.
2. Installing a bunch of modular parts is a little bit of a hassle but relatively easy. Installing a big merged mod is very easy, but for the new user, resolving incompatabilities that might cause would be much much harder than it is for the expert.
3. RP Concerns: It feels more realistic to me to add an area or two at a time because that's believable revitalization. I can just not go to those areas for awhile and tell myself they are being rebuilt or revitalized. Changing the whole world overnight, that's bigger magic than anything I usually RP. Please feel free to snicker at the RP concerns, but I imagine this mod appeals greatly to a lot of RPers. It's the kind of thing we love. Solution: I don't use the mod, or again, I use the modular version so my characters can play through the improvements gradually and it becomes a fantastic and integral part of their stories. That was the plan.
4. Practical concerns: Load order is really important to my game already. I think it is entirely possible I might need modularity to keep some of those little independent mods I love and still be able to use Better Cities. I could download the old versions of course. There is a pattern here.
5. Community concern. This one I don't think anyone has mentioned. If modularity goes away, there is a potential hidden cost to other modders. What if some person comes in now, late, with a terrific idea of his or her own about how to mod an area of the game covered by Better Cities? Then he/she finds out that users would have to give up ALL of Better Cities Merged to use this one city mod or else use an old unsupported modular version. I dunno about our hypothetical modder, but I would give up. It looks like to me that there aren't a whole lot of areas in the game that have not already been claimed by one or more of the biggest comprehensive mods. It's wonderful that the state of modding for Oblivion has reached that point! I'm completely impressed by that and all the work it has been for you and others. I'm just thinking about how hard it is for people who make new body types to get anyone to try them. Why? Because so many mods rely on the existing ones. I'd love to try TGND body, but I'm still using a body mod I don't like as much for compatability and it's a shame that's how it goes with mods. If you merge your mod so it's all or nothing...just please be aware that it's going to severely limit what new modders can do if they ever hope to share their work. Increased standardization has some terrific benefits you've expressed quite eloquently. However, the cost might be that the little modders have to fight over the pieces that aren't claimed yet because very few people are going to want to rule out using Better Cities as it gains more and more neat features. I don't blame them. I wouldn't download a conflicting mod if it meant I couldn't use any of Better Cities. How much unclaimed space in the standard cities is left when all of Better Cities and well known mods that are stated compatible with it are installed? Asking because I've been reading modding tutorials that say something like "We're going to build a house at these coords because Better Cities doesn't use that spot. And guess what? I already had a house that did. I suspect there are probably 10 houses that use that spot or more. You should be proud that modding tutorials now take this mod into account. However it does already make things a bit tougher for outsiders. Something to consider maybe. I can tell that you are people who have gone to a lot of effort to work with other modders, so I thought I would mention it in case it might be a factor for you.
Good luck, whatever you do, and thank you sincerely for continuing to support and develop Better Cities. Even if I end up not being able to use future versions, I appreciate it. I've seen a lot of wonderful mods that have been abandoned. It's great as a new player to see active and caring developers still here.
