JRPGs are infinitely better with a pick up and play capability as far as I'm concerned. Handhelds make them much more easily enjoyed since they also happen to be one of the easiest genres to lose the motivation to continue playing. I only ever got into them once I started trying them on handhelds and the difference is incredible.
In the case of Falcom games, they are mostly released on PSP/Vita which sell abysmally in the west. We wouldn't even be getting Trails in the Sky: SC if there wasn't a PC version.
Having these games on PC will give a chance for way more gamers to enjoy these titles, if you so much want to play them on a handheld you can get a Nvida Shield or a Tablet that can play them somehow(Celceta and Seven are already on PSP/Vita).
Also, it depends from game to game, I prefer to play Ys games on the big screen any day than on a handheld, it's an Action JRPG that's fast paced and they aren't that long. Handhelds are awesome, but we could have both and everyone ends up happy.
