An observation here - Spirit Island, Sentinels of the Multiverse, and Terraforming Mars all fit into the same category for me. I call them momentum games. You start out on the back foot, few resources, unable to do much. As you go forward, you get more and more…momentum? While initially the game is holding you down, you start pushing back and pushing back, and then you start making progress. Assuming you win, at the end you’re wielding a huge metaphorical hammer and slamming those last nails into place with satisfying thwomps.
SU&SD was down on all three, and maybe others in the genre. A lot of people obviously are not.
I, for my part, find them satisfying but uninteresting. I like to play from time to time. I like the feeling that comes as I accumulate my strength and then lift a heavy task that at first feels unliftable. I like the feeling that comes from the slow turn of the tide and the satisfaction that comes from victory.
That said, in my favorite games I prefer, instead, the sparring that comes from interactive tactics. I like it when a game (or opponent) puts me on the back foot repeatedly but gives me the tools to creatively respond. Innovation, Tigris, El Grande, Cyclades.
And this is not at all a value judgment - it is an attempt to articulate that element of taste where our two parties seem to diverge.
