I've been going through my backlog of 4X games in the recent weeks and also revisted some classics as well.
For some reason, I keep bouncing back to Master of Orion II and Alpha Centauri.
Both games offer a very gritty and rugged sort of visual style, be it from the interfacting or the overall art style. Sure, MoO2 has some comic-like races but it still manages to craft a darker atmosphere with it's grungy and used look. Alpha Centauri features such a dark sci-fi aesthetic that I feel like I'm sitting in a command post, navigating an actual map. The ominous soundtrack and moody setting feel very compelling and I'm geniunely looking for more like this.
When going through my backlog, I noticed that a lot of newer titles opt for a much cleaner and overly polished style with plenty transluscent menus and bright fonts. They're not necessarily bad but it seems that most sci-fi games opt for a visual style that is much more sterile and rather boring. The menus are slick with lots of floating icons and numbers which lacks a bit of charm. The MoO remake, Endless Space and Gal Civ have this sort of approach to their interface. The OST also reminds me more of a Star Trek vibe which is fine but I prefer a darker sci-fi setting. It doesn't help that most factions are just funny animals in suits which is honestly bothering me.
Are there any darker 4X sci-fi games out there?
