I went and purchased my first stupid amiibo thingy. In general, I don't like the figurines because I think they're an overpriced form of micro transactions. Also, they allow Nintendo to generate absurd profits without making proper games themselves, so Nintendo can simply use them to bail out other parts of the company that are making stupid decisions.
Notwithstanding those facts, I love Shovel Knight and wanted to access the two-player mode, which is locked behind this dumb figurine (okay, it does look pretty cool, but the figurines themselves are dumb). Since the game itself only cost about $10 or so, I didn't mind paying an extra $14 to get the two-player mode and whatever else the figure includes. I should hopefully post a two-player playthrough soon on Youtube. That'll be fun.
I doubt I'll be buying any more of these things though. There will have to be a really good reason for me to do it.
