A simple question, with a very difficult answer, IMO. Capcom is one of the best developers/publishers in the industry. And they've been a good partner with Nintendo for years, delivering some amazing games and experiences for decades. What would you say is the best we've seen from them?
Draw upon your own standard for what constitutes as "best" and if you can, explain your decision. Let's hear your thoughts, Negative World!
Whatever you do, don't play Miles Edgeworth until very last. Because once you play the best game in the series, all the others just make you wish you were playing as Miles "Doesn't Just Bluff His Way Through Cases" Edgeworth.
@Mop it up As far as I know nothing has been remade in the West, though there is currently some Japan-only remake thingy on the way? But for now in the West there are the original DS versions (+ recent 3DS digital download only) and then the WiiWare ports which are basically just the same games as the DS ones. So might as well start with the first one, Phoenix Wright: Ace Attorney, on DS or WiiWare, whichever you please. And from there they basically go in linear order.
There is also the 2 game Miles Edgeworth side series, only one of which has made it to the West. And the upcoming crossover with Layton.
