I'm not sure I've seen a gaming masterpiece this decade yet... and time is winding down for the 2010's to crank one out. Sure there are games I like, but nothing genre defining that hadn't been done better previously. Mostly this is the gaming decade where games got prettier by sacrificing gameplay, impact, content, originality, creativity... Oh there were also the hardware input improvement leaps forward like 3D, motion control, Kinect, VR before it gets good (if that ever actually happens)...
So yeah, great gaming decade. I feel sorry for the kids who have THIS to look forward to when they are old enough to appreciate nostalgia. Still, I haven't purchased "My Time at Portia" yet. So I guess it isn't fair of me to proclaim that it isn't the "masterpiece" version of Stardew Valley. I really don't believe it will be, but I suppose there is always the chance.
