The trailer got me, I had a smile on my face even though I legit didn't know anything about Xeno
You should definitely get XB1 or XB2 I've seen them on sale quite a bit recently.
They're not the most deep RPG's out there but they're really fun to play. In some way Xenoblade 1 strangely reminds me of those Quintet SNES ARPG's like Illusion of Gaia and Terranigma.
A lot of atmosphere and heart and fast action packed battle systems. In the remaster they fixed a ton of things aside from the visual improvements (on Wii it was hard to make out anything but the terrain really) to make it even better.
It still is one of the all time JRPG classics.
XB2 is more animu than the first and has some additional Gacha elements. You can collect new 'blades' which are characters that help and assist in battle (not unlike the Astral Chain mechanic) by summoning them from crystals which have different tiers and rarity stats. The game has a few progression barriers that require certain blades or skills that they have. Like XB1 the core mechanics still work and the side quests are more modern but there are some downsides to the new gameplay systems especially for completionists.
