Even that doesn't work very well though, because progress accelerates as technology does and you'll get some crazy scaling/movement ratios or players seeing different years on the same in-game turn. I guess my point is that in-game years don't actually hold any gameplay meaning or relevance whatsoever. If anything, putting expectations based on those years is actually misleading in strict game terms. Even a relative newbie seeing extremely variable years on the same turn will quickly realize that it's the turn # that matters. I'm not against cosmetic flavor but in this case I don't see how it even aligns in a way that has a historical relevance/tie, irrespective of which IRL system one might select.
