PS2 cause of the jrpg lineup was untouchable by the other three.
Which is still the case even today with the ps4, xb1, switch
For smaller jrpgs yeah but what about triple A jrpgs? games like main line final fantasy, kingdom hearts, Nier: Automata, persona 5 and so on.Had to vote PS2, though they're all great...
I do have a special fondness for the original Xbox though, since it was my first console from that era.
I wouldn't count the Switch out on the JRPG front. PS4 definitely isn't untouchable, it just has a decent headstart. Nintendo's portable systems have always seen good JRPG support, and the Switch is already shaping up nicely in that regard.
