Yes to the Donkey Kong Country games. They don't necessarily need it or anything but those are among my favorite games ever, and that includes the third one (I love it for the variety, very few other platformers added as many different level concepts and gimmicks as they one, some of them were totally busts and I can never truly forgive them for removing Rambi but I still love that game). I would love them all tied neatly into a bundle, I don't really need the graphics to be updated since I love the aesthetic but if they packaged them all together and maybe added a feature of being able to take different pairs through certain levels. What I mean is, if there was a mode added in where you could take the duo of Diddy/Dixie through levels of the original Donkey Kong Country, or Donkey/Diddy through levels of DKC3. Kinda like a Knuckles in Sonic the Hedgehog 2 type deal.
But I actually came into this thread to say, and this will probably never happen, Xenosaga Episode I. Probably my favorite RPG of all-time, and I would love to go through it once more this time with trophy support. Considering the series had cutscenes that lasted 20 minutes, a total of 8 hour of cutscenes per game I believe, trophy support is kinda a necessary component to get me to play it again. I don't quite have the time to justify a third go-through without it.
