I am surprised that someone prefers Xenoblade X over Xenoblade 2. That is kinda rare.
Well, I don't think it can't be that kind of rare. That being said, yeah, X is definitely my favorite Xenoblade game, it probably has everything I ever wished to appear in a video game. Too bad I don't have my Wii Us right now and can't play it again. Should do it right now, while the squad missions are still available.
Now, between Xenoblade 2 and Skyrim... Skyrim, no contest, it's the better game and by a lindslide. However, there's a lot of charm in Xenoblade 2, but you'll likely need to get over a good bunch of things, mainly 2's atrocious sound design, the overwhelming mechanics, a rather poor technical display, the divisive art style, the weak cinematic direction, poor narrative, and so on. Regardless, it's still one hell of a game, one of the very few ones that are worth it on Switch right one (well, among those ones I currently own, it's one of the two).
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
