A long time ago . Some of the earlier deity players. I initially posted in this thread because I thought it was interesting that the modern HE sounded a lot like the old time SE. (I haven't been reading archived strategy articles BTW . Not that there's anything wrong with that ). SE is a misnomer in that you don't actually get the majority of research from your specialists. But as far as you can make a decision about where to get your non-capital, non-terrain commerce, non-trade route, non-tech trade research, it makes sense to differentiate between the cottage spam and specialist routes. Unless no one even does cottage spam anymore in which case it's entirely pointless .
