I don't see people mention Cross Codes often and no one has mentioned here yet so I think it's "lesser known".
It's one of the games I got. I'm 20 hours in and the game is amazing so far.
The game can be pretty challenging sometimes so I'm not sure if it's for everyone. I'd describe the game as a MMORPG but without the MMO. It has a lot less grinding than a MMO and a lot more puzzles.
I saw some people compare it to Zelda but I feel like that's only accurate for some aspects.
