Disclaimer - I have never played this game with other people, only single player. I would actually wager that very few people who’ve played this game have done so with any more than 2 players due to how difficult it is to set up a multiplayer session - requiring a GameCube, a GBA, 4 link cables and three friends with another GBA apiece.
While the GBA linking concept is utilized in a creative and interesting way, the high barrier to entry for even playing this game as it’s intended is definitely a massive negative for the title as a whole.
That said, unlike the version of Four Swords on the DSi, four swords adventures actually has an enjoyable and well implemented single player mode. Arranging and switching between links is seamless and intuitive and it’s actually pretty easy to multitask with them and have the links do different things in quick succession. This mostly comes into play during boss battles, which are generally high quality.
The level design in this game is similar to the original four swords i.e pretty different from normal Zelda games. Most levels act as a sort of mini dungeon - even levels that take place outdoors - where the links will proceed down various linear paths and sometimes backtrack when new paths are opened by player actions. There are a couple levels that switch things up by acting more as puzzle boxes where the player has to talk to different NPCs and complete tasks and puzzles to proceed.
Combat generally feels good and is actually a bit more involved than most 2D Zelda games due to the expanded combat mechanics allowed by the four links.
The biggest flaw this game has - apart from the high barrier to entry - is due to how it breaks from the classic Zelda formula that fans know and love. While the mini dungeon focused design of FSA can be fun it’s not nearly as refined or engaging as the classic Zelda formula that Nintendo had perfected by this time. Four swords adventures if just sort of boring to play. It’s very repetitive and neither puzzles nor combat involves much challenge or engages the player in creative ways. After the first world you’ll have experienced pretty much everything this game has to offer. If you want to actually finish it you’re going to be in for a very boring and repetitive experience.
I’d only recommend this game to hardcore Zelda fans who want to see what it’s like. If it ever gets a remaster and playing with three other people is more practical id definitely be recommending it to more people. However, as it stands, most people trying this game for the first time in 2023 will probably be playing single player which just isn’t a terribly worthwhile experience.
