Look, I'm not jumping on any bandwagon or shitting on anyone but there has only been one previous merge for this game with 'Week One' and that took 8 weeks (iirc) and it was said that 'they' (
the dev team) had learnt their lessons and
any further merges wouldn't take that long. Well, Month One is 3 weeks merged into one update and it's taken 6 months so far, which works out to be about 8 weeks for each week. So it's about the same schedule as the previous 'merge' but it's longer than I think they were anticipating by quite a margin.
I find it encouraging that they announced that the next major merge would be the 'year one' edition, as I think they've realised that going in with a perfectionists view of 'fixing' everything can really derail your dev cycle, but fucking hell I don't want to even guess how long the 'year one' merge is going to take....
