If this appeals to you, I'd highly recommend giving Star Wars Squadrons a try in a high end VR rig. The game overall isn't perfect, but it's by far the closest I've ever felt to feeling like I was flying a tie fighter or an x wing.
Battletech always seemed trapped in a 40k-esque lore vise of its own making, in such a deep focus on a specific slice of time that progressing the greater narrative forward seemed inconceivable.
But I guess that's tabletop-derived worlds and games in general.
Squadrons is a blast in VR but I wasn't the biggest fan of the feel of the flight model. Especially coming from combat in Elite:Dangerous with much nicer cockpits, etc.
I wanted to love it to death in VR because it looked so nice but the flight model was not my piece of cake.
The cockpit immersion was so good.
My biggest gripes with Star Wars Squadrons are the poor campaigns, or lack thereof, and ships tuned for competitive multiplayer only.
Editing to add, I just saw your user name, and at first assumed you created it just to reply here.
