It's funny to see how some people complain about "Nutaku never learning on their mistakes", because the ones who never learn is players themselves - the ones who keep Nutaku afloat by giving them money, playing their games, even simply visiting their site. I mean, Nutaku already proven themselves being bad at management, support, basically everything (except from PR). And yet people continue throwing their money at them...
Well, I blame the devs. Although not as much as I blame the devs of Aigis. In this case, it kinda just seems like they got in over their heads...
Personal favorites, by game:
Millennium War Aigis (RIP): Liana
Girls Kingdom (RIP): Iris
Dragon Tactics: Memories (RIP): Diske
Brave Girl Ravens xR (RIP): Francette
...Most of the games I play on Nutaku end up getting taken down. Hmm.
