If you ask me this is searching a tad far, yeah its possible but why even?
Games compete with one another for playerbase. All the shooting-game FPS games pull players from each other. It's a popular genre but as you can see, lots of people like different flavors of "shooter game" to suit their play style. Some like a 3-minute Overwatch game, others like structured 5v5 CS:GO matches, others like battle-royale based shooters, and some like survival-shooters like Rust. The core gameplay for these is basically the same, and as such FPS games are generally popular from just having a bunch of interesting weapons and ways to kill your enemy. Only the flavor of how you shoot to kill your enemy really changes, and what you do before and after that event. Basically, if you took the gun play out of any of those games, those types of games are completely dead.
Starbase is an MMO but doesn't compete with WoW because WoW has quests, a story, a world to explore, end-game raids and is level and loot based. So it's not included as a competitor, although people who enjoy the persistent world of an MMO might enjoy Starbase.
So what I'm pointing out is that, since Starbase is a competitor with the big-deal FPS games, and also competes with Minecraft, and competes with spaceship style gameplay like No Man's Sky and so on, it's in an amazing position to grab a lot of market share because it has a little for everyone. Combined with the online game world, you get the WoW-style meaningful gameplay where your faction depends on you (like WoW groups need their 40 people for an end-game raid). This potentially captures some of every one of those games out there.
A new shooter game for example - like when Rainbow Six Siege came out - only competes with the FPS shooters directly, and then also only competes with the structured 5v5 style FPS games (not Rust's secondary gameplay, for example). The fact Starbase is knocking on everyone's door is a big deal - and if the networking can keep together a huge gaming universe... what... you're going to go a) play a meaningless match of PUBG or b) go raid a faction-owned station in Starbase and enjoy the same kind of gameplay where you have to be the last group alive on the station to capture it. I see Starbase securing a lot of the gameplay from other games, if they can make sure all the gameplay in Starbase remains meaningful, which is the main unknown at this point.
