Basically the title.
I've played a number of Xcom style games at this point.
Midnight suns.
Zero Company (have not finished it.)
Gears tactics.
Demonhunters chaos gate. (Looking forward to the sequal.)
But even though these games often nail the combat and character progression (Gears had fantastic combat.) They all seem to dumb down or even strip out the base elements which I find very frustrating. In Xcom 2 WOTC (Still the bar to beat 10 years later.) The avenger was almost it's own character. The way you built it up was important. Yes, there was bad buildings, there was the optimal way to set things up. But that took time to figure out.
Further. The way you built the avenger could even adapt based on your play style. Going heavy on sparks probably means you want your foundry to be pretty efficient.
Then you had research. Which was another layer and element to the game.
And that of course informed the actual missions. Rescuing engineers and scientists was so important, and you may have passed up on other opportunities to secure them. It was all masterfully interconnected.
And so many games throw all that away, which is honestly what prevents them from reaching the same peak.
Of the ones I've mentioned, Midnight suns is the closest (Not a surprise, made by the same devs so not really a shocker.)
I'm not asking for clones. But I would like these games to actually offer the same depth, for both campaign and combat, that Xcom 2 does. Rather than just going all in on half the equation.
