The camp is a large part of the appeal. Think Japanese sci-fi B-movie that never takes itself too seriously. If you can appreciate bargain bin monster movies, you’ll probably dig the goofiness of EDF.
Gamplay-wise, it does get a bit repetitive, but the more recent titles have improved on that somewhat by allowing for more organic progression without having to do quite so much grinding for armor and weapons.
How do you handle merging between devices? Do you manually transfer/sync every time you add a new password?
Not trying to sell you on putting it in cloud storage or anything, but one really nice benefit to doing so is automatic merging through clients like Keepass2Android. If I add a new site to my phone and it doesn’t already have the latest copy of my vault, it’ll fetch and merge that first.
