Got my mech in Xenoblade X. Was about 24 hours in, but I could've gotten it sooner since I ended up dicking around a lot today. Mechs are real cool. They tread a weird line between being their own character in battle or just being equipment. I like the way you determine the skills you have via the gear you put on, though I definitely need to make a setup that actually supports each other. My skills are way too disparate as is. Also, the way you can customize (nearly) every color of the design is awesome and 100% the way it needed to be.
On another note, the mission you had to do to get the mech where you had to get 15k or so from resource points in one go sucked. Sure it forced me to learn how to use those systems better, but it felt like the game gave me just barely enough to get by. Was difficult to come up with a correct setup to get me there.
