I motherfucking luuuurrrrvvve a good JRPG, but they are harder to find than you'd think.
For me it's just easy adventuring. Most of them are built on the jouney format (start as a nobody in nobodysville, and branch out into the world until you ultimately save or doom it), and the good ones just make that journey fun. It really is just interactive story telling, but done well you can just chill the fuck out and lose yourself in one. Ideal for unwinding.
Chrono Trigger is way overated and a bad place to start IMO. It's got it's plus points and I do like it, but it's not got the mystery or wonder which a lot of other JRPGs do.
My personal fave JRPGs are:
*Shadow Hearts Covenant - Wonderful setting, good characters, fun combat, cool story woven into real life history. A little flakey towards the end, but a great game.
*FF5 - Mint job system, great pacing,
*Phantasy Star 4 - Just flat out awesome all round.
*The Last Remnant - Really cool & off-centre JRPG
*FFX - Just a fantastically told story with some brilliant characters. Very linear until the end, but that didn't bother me one bit.
*Lost Odyssey - Probably the most well rounded JRPG ever. Takes all the previous years of learning, and refines all those aspects into one game. Superb depth to the backstories.
*Shining Force 1 & 2 - Mint simplistic turn based adventuring. No frills here, you go on an adventure to kill the big bad, you get as many team mates as poss, you do cool things.
I just remembered I heard good stuff about Secret of Mana, anyone try that one?
Another overated game. It's OK, I've finished about 5 times over the years, but it's pretty "meh" all round tbh.
Any JRPGs that aren't light hearted in tone?
Shadow Hearts Covenant. It has some great humour, but the overall tone is very dark. Lost Odyssey too.
