Details, details. My issue was that you spend that amount and get nothing for your efforts. With DMM, the cost is mitigated.
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.
