A usual plan in games as in stories is to have a satisfying beginning, middle, and end. In games, that often means a bit of feeling out the game and exploring the space, seeing how the variability came out in this game, with some balance between rewarding exploration and early specialization. I feel like Pandemic and Agricola are games that require almost immediate pursuit of long range plans to be effective, otherwise you get behind necessary curves and realize you needed to be planning ahead several turns ago, in a game with not that many turns per player. Commenters: care to recommend other games that do this well or badly?
In a competitive game, accelerating the endgame can be a strong strategy, although it can be taken to absurdity. Most games that allow an early rush to the finish have an easy counter to it, so there is the standard rock-paper-scissors of early rush, balanced defense, and immediately building for the late game. Is calling for “no rush” games still a thing, for people who want paper to be the only option? I remember Blizzard discussing that in Starcraft balance, explicitly considering an early rush a legitimate and risky strategy, so no they were not nerfing scissors. (Pandemic is cooperative and Agricola has a fixed length, so perhaps this paragraph is just digression before the topic comes up in comments.)
I tend to be a strong strategy gamer, and there are certainly times that I like being reward for immediately being goal-oriented, but I do like a bit of wiggle room for exploration and unfocused fun, and it feels like a nasty surprise on the other players who were not starting their endgame plan on turn two. It feels a lot like games that give you lots of options, but on the highest difficulties only one or two of them are really viable. In a competitive game like Agricola, you can just play with people who are also content with somewhat lower scores and we all play in that league. In a cooperative game like Pandemic, we all lose if someone is not on the ball, so it leans towards the degenerate problem of one player effectively making the decisions for everyone.
