Zelda OoT and MM. I count them together cuz they’re og and sequel. I love going back and forth as kid/adult. And unique mask powers. Completely different world in both games but you see all sort of parallel between them.

Jak 2 & 3. Story and gameplay was so good for me. It’s kinda like GTA but it’s own style. You can steal vehicles, get weapons, ammos, doing missions, etc. I do love GTA SA too. But Jak just hit different for me.

Star ocean til the end of the time. One of longest post main contents I ever played. Unique playstyle and multiple endings.
