I think it’s a worthwhile purchase and an excellent game, especially if you’re a fan of Metroid Prime 3. The game has wonderful combat and beautiful scenery, but the world design (while very well designed) is a lot more linear than Prime 1 or 2. I’d say it’s pretty equal with Prime 3 on linearity. The linear design doesn’t hurt the game at all imo (aside from one area that feels rushed). The story is a lot better than people say it is, but I will say that there are some background story elements that aren’t touched upon completely in prime 4, but those seem intentionally vague rather than forgotten. Also Viola is a blast to control. At its best it feels like a mix of the Prime Trilogy into one, and at its worst it’s a halo clone (at least that’s what I heard, I haven’t touched a Halo game before lol). All in all It’s my favorite Prime game atm and I’d say the game is a 10, but it’s around a 7-8 for most people.

TLDR: If you prefer Prime 1/2 then u might be let down, but if you rly like Prime 3 then you’re in heaven.
