Man, what sucks the most is I was REALLY looking forward to the new Olympic Games for once.
But the character crap literally just made me lose all interest. What a wasted opportunity.
IMO the series has started going down since London.
London itself isn't bad from what I hear, it's actually really good, at least the Wii version. However, they started with the character restriction stuff in London 3DS. In that game, you couldn't even select what character you played as in an event, you were just given a random character of the available ones for that event. It also had a stripped down story mode compared to the one in Vancouver DS.
Then we got Sochi which was just lacking in content and didn't even have a portable version, and then we have Rio which just seems like a mess to me, even getting rid of Dream Events.
And the annoying thing is, it seems like another Ultra Smash situation. The gameplay has gotten more and more solid as the games go on, but the content is just getting more and more lacking, which kills it.
