Live-A-Live is probably the best game similar to Chrono Trigger since the whole non-random battles element came from there (and the SaGa titles). That and several of the team members that worked on Live-A-Live worked on Chrono Trigger. Also, the whole OST is by Yoko Shimomura, the lady who did the osts for;

• Kingdom Hearts
• Street Fighter II
• Super Mario RPG
• Legend of Mana

The Remaster is well worth it and fixes a lot of RNG issues that the original SFC version had.

If you’re familiar with JoJos, it basically pulled a Made in Heaven through one of the main characters. If not, it just does some funky parallel universe/time traveling shenanigans. It gets real wacky real quick, real fast but it sorta kinda makes sense in the end. I won’t spoil how or who, but it’s worth your time finding out.
