If you started on 3, is it worth going back to play 1 and 2?

I'm not sure if I'm crazy about the idea of going for the completionist emblems in 1 and 2 (seems frustrating? Maybe not too bad at least in #1? Already done a lot of grinding in 3 for fun/xp/money so might not matter much), but I started 3 and am enjoying it, am as far as looking for the fairy for the dark (?) cave.

Trying to decide if the fun might be worth it to go back and play 1 and 2 as well, or if I should just stick to 3? I'm waiting to find some Denpa Men in 3 anyway before I get much further (or transfer from an earlier game, mostly looking for standard healers, I know I can QR, saving for a last resort).

Four looks like it will be a little too heavy on the microtransactions for me.

Thanks for any opinions, fun gameplay.

They'll feel archaic as hell, but they're both very enjoyable in their own regard, so I would still recommeend them, especially if you plan to transfer Denpa forward from 1 and 2. :>

I may give it a shot then, thank you! Largely "paused" in the storyline in 3 anyway due to grinding, hunting dempa and whatnot. :)
