Went in with low expectations, and I ended up very pleasantly surprised! Well done, Nintendo!
MP4 looks great, a new Mario & Luigi was an even bigger surprise for me (and a most welcome one!), always happy to get a new MP, too! MvC making a return (especially MvC 2) is fantastic as well.
And then there's the showstopper for me. Being an Ace Attorney fan, I almost screamed in the bathroom at work with the announcement of the Ace Attorney Investigations collection! Now I will be upfront, the first game is generally regarded as one of the weaker (if not the weakest) game in the series, which I do agree with even though I personally had fun playing it.
The hype is all about AAI 2: Prosecutor's Gambit, as it's been the only AA game that has yet to receive an official translation/localization. (And it's been out since 2011 and didn't get a fan translation till 2014.) It's always been lamented in the fandom since the 2nd game is not only a major improvement over the first, but it's often praised as one of the best games in the entire AA series! For me, it's right behind The Great Ace Attorney as my favorite, and I'm super excited that more folks will be able to finally play it!
