That's unfair. 1UPT against an opponent with a pulse is also a completely different kind of game. I'm fairly certain the vast majority of civvers play SP primarily. When people criticize SOD, it's exclusively on the SP game against the AI and how the base AI encouraged mechanics of SOD. There hasn't been a good argument in favour of SOD, usually the critique of 1UPT criticizes its faults and downplaying its advantages, perceived or imagined. But rarely does it link back to justify bringing back stacking outside of some who feel attachment to stacks. It's arguing from a negative position, whilst people who like 1UPT will only need to note the SoD and move on to pointing out all the neat tactical things that happens in a map with 1UPT. Having been with the franchise hardcore with Civ3, I am unabashedly pro 1UPT and all its variants - limited stacking, combining of units etc.
