Hey any advice for getting into the Xenoblade series? Where do I start and what should I skip?
I am what would be called a Xeno-Boomer, so my reccomendations are biased against the new weeb versions of the games.
Xeno is not just Xenoblade, it goes back to a PS1 JRPG called Xenogears, the game ran out of time and was released with an unfinished second disc. There was an entire story plan for 6 games, the story outline of the first 5 games was released in a book called Xenogears Perfect Works (there is a translation available online, read it after playing Gears). Square screwed over Xenogears 2, instead using the funds for their shitty final fantasy CGI movie, so the Xenogears team left Square to found Monolith Soft, they then made the Xenosaga series, which was planned to tell the entire 6 game story, but due to poor sales of Xenosaga 2, was cut to only 3 games. Nintendo bought monolith after Xenosaga 3.
Xenoblade Chronicles on the Wii is not technically part of the 'xeno' series, it was originally going to just be called 'Monado: Beginning of the World', but Iwata said that the themes of the story were similar enough to the Xeno series, so he made them call it Xenoblade. It's important to remember that Xenoblade 1 was always a standalone title, they later retconned story changes from Xenoblade 2 they made to forcefully adapt it into telling the Perfect Works story in the Switch remaster, its just some tiny things, visual only, but I'm a purist so it bothers me.
Xenoblade X was announced for the Wii U and is completely disconnected from Xenoblade 1 other than sharing the Nopon characters, and some references or easter eggs. Xenoblade X was made with a lot of the original staff that worked on Xenogears, specifically the original character designer who worked on Gears and Saga. Xenoblade X plays like Xenoblade 1 but refined and taken to its logical extreme. It's absolutely a hardcore JRPG, where Xenoblade 1 is pretty easy and you never really need to fully learn the systems, Xenoblade X requires you to understand its systems or else you can hit a wall and not be able to progress. Xenoblade X seems to be their attempt to return to trying to tell the Perfect Works story, but due to the game being on Wii U, and Nintendo making them add online features (which meant they had to scrap the story they had written in order to accommodate custom player characters and stuff), the game didn't do very well. It's personally my favorite in the 'Blade' series, it has the strongest gameplay.
Xenoblade 2 was started development at the same time as X, it's a soft sequel to 1, you don't need to play 1 to play 2, but its probably a good idea. Gameplay is much more simplified compared to X, a lot of interesting systems were cut or streamlined down. It's a more casual game. I'm not a fan of the artstyle change, and I personally don't like the story. But its still a good game. My issue with it is that it brought in the Persona fans to the fanbase, the ones that care more about shipping characters and jerking off to Pyra than the actual game. Regarding gameplay, its much slower than XC1 or XCX, based more on attack canceling and combo building. I found it really easy, but perhaps that's because I spent so much time playing XCX. The story does drag a little bit, but thats because Nintendo took most of the staff to work on BotW, a lot of the game was outsourced, and you can see that in the Blade characters, they are all done by different artists so the style completely contrasts.
Xenoblade DE is the remaster of the first game on the Wii. Personally I'm not a very big fan of the character artstyle change, but that is the new artstyle they are keeping going forward, nothing I can do about it. The game is mostly unchanged, other than the before mentioned visual retcons. They re-recorded some music, its preferential, but if you are playing the Switch version first instead of the wii version I always reccomend people use the original soundtracks. Other than that they changed the UI to make it in line with 2. There is a post game epilogue added, which just wraps on some character threads, entirely optional but its pretty good.
Xenoblade 3 I think has the best story, I didn't like it at first, but after replaying Gears and sitting on it I'm coming to appreciate it more. 3 is the literal mix of 1 and 2, the world, gameplay and characters are from the respective entry. Gameplay is a blend between the faster style of XC1 and the slower combo of XC2, its still too slow for my taste (again, I played a LOT of XCX) and it struggles from battles just taking a long time due to having 6 active characters in a battle, so they output less damage per character. 3 has a LOT of references to Gears, the plot is pretty much ripped from a plotline in Gears even, the main character is named after Project Noah, the codename for Xenogears, he even looks like Fei.
I never finished Torna, the DLC/Expansion story for Xenoblade 2, its a prequel that goes over story events that get covered in the story of 2, and you already know the ending if you played 2. I didn't like 2 enough for me to really even get into the backstory or care enough about the gameplay to really enjoy it. It's just more world building for 2 pretty much.
As for playing the series. I reccomend you at least play Xenogears on the ps1, before or after you play the Xenoblade games. Its a rough game, but its the foundation of the series, and has the best story of them all. Absolutely play Xenoblade X though, it runs really well in Cemu these days, and you can even use some graphics packs to boost FPS to 60+ and access online content alone. Xenoblade X still has the best gameplay in the series (the ENTIRE xeno series) and its just a good time to play. The main storyline is pretty weak, but the core of the game is in the sidequests, characters, worldbuilding and gameplay.
For playing the numbered games, I always recommend people play the Wii version of Xenoblade 1, but if that's not possible for you, the remaster is fine. You can play 1 or 2 in any order, but you need to play both for 3 to truly shine.
