She mostly says that because she's a fan on UN and not GG, as for me I can't say much on GG. But uh if it's anything like BlazBlue, it'll be fun to play but you won't understand a fraction of what's going on. The good thing about Under Night is it's actually new enough that the characters and lore can still be picked up. Though it's not as over the top as the likes of BB/GG.
