You hunt Monsters. A typical mission consists of tracking down a huge boss-type creature and battling it for an extended period until it finally goes down, then you use materials from its corpse to craft new weapons and gear to fight bigger, harder monsters.
In past titles, was it possible to fight the harder monsters first and then the low-tier ones? Or is it going to be possible in this one? That could be interesting. Although I don't know if I'm missing the point in something that makes crucial to fight monsters in a more sequential order. The basic premise is very tempting, though. Sounds like an ideal time-sinker.
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.
