FFXIV on the vita can be done.  Right now Im trudging my way thorugh the Heaven's Ward campaign 100% on the Vita.   I even finished all of the content leading up to the expansion (incuding all of first coil) on the Vita as a Dragoon.  My hands hurt afte a while using it.  Going back and forth with the tap sensor on the back of the Vita for alt menu's can be tiresome.   But it is doable.  Im willing to give something far more leeway than I think most people would. My bullshit tolerance is level 99.   Dungeons, and Trials and raids.  All can be accomplished. 

I agree with this statement in full.  Its a great X-men 2D game.  The inclusion of Psylocke also makes it pretty unique up until Capcom allowed us to use that character in their fighting games.  

The Mega Man X games did have a bundle released on PS2 and Gamecube.  THe GC version costs more and I think is considered the better release between them.  The Music and controls are off with the PS2 version.  It might be cheaper to pick them up on the Wiiu virutal console than trying to score a copy of the game with case and manual.
