Why are you Trying to Reinvent the Wheel
This will probably come off as extremely toxic but simply this is the way.
If you want to remake X-wing Vs Tie Fighter, please just do that..Don't make a game that is essentially multiplayer only.
Now multiplayer only games are fine, but this isn't CS:GO or Valorant what do you think the chances are that you're going to release a game that is at e-Sports quality multiplayer?
I think this will be the test for you on what makes a good game (regardless of what people say they want).
games that WILL be successful no ifs and buts
Kotor 3
Jedi Academy 2
X-wing Vs Tie Fighter 2
Remake them to the tee and for the love of god don't have any ideas just imitate them please.
I don't know why you torture yourself and us with these decisions, its like rise of skywalker/Last Jedi decision making levels.
