I played Pokemon
Colluseum Colosseum. It was pretty good.
The difficulty curve is a lot steeper than the main series, so grinding is pretty much mandatory if you want to beat the whole thing. It doesn't really help that the AI cheats and reads your moves before picking its own. The graphics aren't great in the light of the modern day, but passable. And to my surprise, the aesthetic direction and writing was stronger than in the handheld games; some of the environments are quite pretty, and I actually laughed at a couple of the gags.
Of course, it's mainly just about seeing your 'mon to scale, which I'll admit is pretty entertaining.
Sadly there's no lineup screen at the end, so here's my team.
Oh, and for the benefit of Bullet Magnet here's a .gif of an owl firing a laser beam.
