Kind of like an announcement from your car manufacturer that
As of version 1.79, REVERSE GEAR IS BROKEN, do NOT use it.
Overall I think MoO2 is more playable than SE. MoO1 probably even moreso, though MoO2's individual ships and more detailed planets (the city part, anyway) are nice.
SE is awesome, partly because it feels like the developer really tried to put in
all the things that people ask for for a 4X. Even being able to literally preposition all your units at a particular place battle view (in SEV, at least), just as part of a normal turn.
But packing all that stuff in there really seems to cramp out playability. I feel like I'm interacting (carefully) with an ancient, eldritch device rather than playing a game. Fun for a while, but ultimately the frustration that "if it would only let me express my orders more concisely, and be more responsive, this thing would be 100x as much fun" wears down my desire to keep playing it.
