It’s a narrative game. The graphics are intended to be more functional than pretty.

I also wish there was more voice acting, but the problem there is likely that you’d need the entire Voyager cast to chime in to sound right and there is a lot of dialogue. Not to mention, even the voiced logs with Tim Russ / RDM sound off because they’re 30 years older…

As for 6GB of VRAM, I blame the engine if that’s a real number and not one from the recommended specs (which are probably more about GPU power than memory). This game runs on Steam Deck and it technically doesn’t have any VRAM.
