Those rapid releases will be coming mostly for bugs or urgent balancing. Maybe one of the skipped features will appear or two... I played Adventure Mode just for 2 months (trying my new cpu out). I am Fortress Mode dweller lol. Adventure Mode has some fundamental issues in crash/lag bugs. Some missing features too. However the thought behind, that bug fixes and missing features should be coming on yearly basis, even if new system will take 2 years is, there are so many of them. One 3 months long session of rapid fixing will not patch it even on surface. Just check development pages for still missing implementations of old systems. Furthermore adding more unfinished and bugged systems will just pile its bugs and rough edges on top of older system bugs causing spinning out of control issues, which can be not fixable without entire older system rewrite. So, yeah I would say Toady should keep making one system per one time (a big wait after big wait) so long it takes, until he is finished with them, but bugs fixes and still missing features should be coming on yearly basis as well as continued balancing to all already existing systems. So imho maintenance cycle should be 3 months each year, no matter in which point the big wait is in... Keeping things this way, would maybe give few patches to the engine turning abstract world into real world and real world back into abstract world. Keep it less glitchy, you know. That would surely give Adventure Mode a second youth in a way.
