After playing SC4 on and off for the better part of a decade, I've decided to give the CAM a try. So far it seems pretty good even without installing high-stage lots - farming is now relevant, there are bug fixes and general improvements, etc.
However, I'm having a hard time getting I-HT and CO$$$ lots to grow. I have everything that I would have thought would be sufficient - demand is enormous, there are plenty of well-educated residents nearby, desirability looks adequate (green) in the data view, water's provided, etc. It looks like the culprit may be that CAM's increased the desirability threshold of high-wealth developers so that they're extremely picky about where they grow, per page 12 of the CAM 2.1 manual and per this discussion.
Problem is, RippleJet admitted in that discussion that a desirability threshold of 120 is almost impossible to achieve and therefore makes high-wealth development extremely difficult (this was in the context of CO$$$, but I originally noticed it in the context of I-HT, since my industrial zones were sitting undeveloped if I suppress dirty and manufacturing demand via taxation). That was back in 2011, but it looks like the 2016 CAM is still using those original values.
Is it possible to modify or remove the increased desirability thresholds associated with the CAM? If not, what other workaround should I use to get high-wealth development - placing new parks everywhere every five months to get the "transient aura" effect?
Edit: I should add, I'm posting this here rather than over at sc4devotion because I'm not sure how active that forum is - the CAM subforum has not had any posts since November.
