I really hate this reductionist attitude towards the game. I can promise you there are much more than 5 types of systems - there some 15 star classes, but then there are giants, sipergiants, you have planetoids, star orbiting othed stars, planets orbiting pulsars, moon-moons, sheperd moons, hot jupiters, gas giant pairs and many more variantions and that's just orbital mechanics, before you even get planetside or before you see the dozens of space anomalies. Stations, yes, are about 5 main types, but there are settlements, outposts, the odd science station and megaship, tourist outposts etc. The game offers a diversity in exploration that i've yet to see NMS match, despite it having landable earth likes and alien life. And Starfield somehow can't even match what's in NMS, despite todd bragging about exploration being the main focus.
Elite is a game about flying your spaceship in a space sandbox. If you like the flight model, the combat model, the symphony of sounds your ship makes you're gonna love doing whatever with it.
Now the game has plenty of flaws, and yes it is grindy ( or it used to be, as it's been lessend lf late ) but anything is grindy if you're just doing the same thing over and over. If you find you liked the game but got bored with it, maybe join a community, or join an outgoing expedition. Elite's community is unmatched in its awesomeness.
Apologies for the rant but I hate people besmirching the good name of Elite.
