Though I haven't played thru Ark on PSP, I don't recall any choppiness, just long load times. Anways, my fav is probably Origin, I loved that game, I'd have to say, atleast at the moment, after that, would be Oath in Felghana, & the Dawn of Ys. The PCE version of Ys 3 was my first, pretty easy to beat in japanese actually. I do love that game, probably cuz it was my first, but, it's not my favorite. BTW, where's the voting area for the PS2 versions of 1-5?? The DS 1 & 2 is....ok, but, thankfully Falcom ported over the Eternal/Complete versions to PSP, unfortunately, probably no one will pick it up, thanks to Atlus picking up the DS ones
though I wasn't totally happy with their translation of various names & places. As for Ys 7, it has no jumping, believe it or not, but, I'm hearing it's awesome, & am hoping it will be brought over in some manner, whether it be PSP, PS3, etc. I doubt the PC version would ever get an english release outside of an english patch by fans.
