>>11879593There's kind of 3 eras you can jump in
Kaga is the OG era, you can really feel the TTRPG design philosophies in them. I think Tear Ring Saga is a somewhat plain but least frustrating in all his designs, Vestaria Saga being the easiest to obtain since its on PC.
The OP is referencing the classic era which all are just solid packages. While you can go chronological
>>11879658 just know that the prequel (7) smoothed out a lot of the rough edges and is the entry point for most NA fags. Otherwise if your want 3D, PoR is good if you can deal with the wet noodle animations.
Then there's the nu-Emblem with Awakening on and they're perfect if discover you're turbo-autistic about build comps, but genuinely uneven messes for everything else. If you're on VR asking, I don't think you need the low barrier of entry they throw around.
Personally the series is best when it leans into its simple, elegant core and avoids the bloat. I think 6/7 is solid foundation to go back to the Kaga games (4&5 specifically) to really see how impressive they are despite their many flaws.
