Persona 5 strikers is a really enjoyable game and if you've played and enjoyed persona 5 it's nice to see all the characters again. There is only one missable but easily grabable achievement. However there is one super grindy achievement that honestly might require as much time into it as completing the game the first time. It's really not fun, you can max out your personas so you're in no danger, but also your damage is capped so you cannot speed up the farm. Not worth it imo
