* Star Trek: Bridge Commander aka BCFiles is back! Now on Gamefront! https://www.gamefront.com/games/bridge-commander
Only thing I can think of is that the artist googled Excelsior refit and used it.If you search Excelsior Refit, that design does show up for some results.
So what? Using someone else's artwork without their permission is still plagiarism and liable to a lawsuit. Just because CBS can and does steal from their fanbase, doesn't mean it's the right thing to do. Big corporations love to steal from their fans, and then expect the same fans to keep funding their sub-standard trash.
