is it worth it to play oni's current?
More characters. Some content that isn't available in Prime (althought also it's lacks some content that is). Some animation differ (and sometimes silly funny). Game still can't handle interactions with more than two girls in one room.
If you aren't afraid to get some weird bugs then sure it's worth it.
And I don't believe Oni build will ever be in stable condition without outside help.
Poor Prime, reading Oni's vodoo spagetti coding almost broke him unrepairable much more effective than any decepticon.
It's really like necronomicon.
