I found the interactive turn based combat in PA Adventures pretty fun and engaging, but it's certainly not for everyone. This also reminds me of another gem.
Barkley, Shut Up and Jam: Gaiden - This is THE JRPG parody/deconstruction featuring your typical post-apocalyptic JRPG spiel, except it's all about basketball and Space Jam is considered a canonical part of the storyline. You'll run up against all the typical JRPG clich?s only they're turned on their heads. To top it off, it's free. Unfortunately the official site is dead, but a few of the mirrors from the link should still work.

The PST of JRPGs, if you will.
