I wouldn't call nutaku ever trustworthy.
- They shut down games without any explanation.
- Lack of updates in free pools and horrible rates on summons and stuff turn the games even worse.
- Their translation ain't that good in most cases, i remember some cards on games such as Dragon Providence(yeah, already closed) with errors as if the translator was high.
- They make deals with "Sakuragames" chinese publisher. For those who ain't aware, even non-official translation groups or solo translation ends up better since all this company does nowadays is to throw stuff at google translator or similar program and then sell it as if they actually worked on it, not ignoring the fact that they don't even have licence to sell most of their stuff and were already sued many times... and yeah, nutaku got a deal with this shaddy group selling their stuff.
Basically, in this page, ur money matters and ur opinion not. I've followed nutaku since it started and not only aigis was closed without any explanation, they actually closed more than 10 games that were originally published by dmm, however dmm nowadays started their own translations and english games as well, probably wanting to disconnect themselves from nutaku, some people used to say that dmm servers and rates were always better(WAY BETTER) than nutaku stuff and their lagged events in-game. Well, up to ur own opinion, my personal remains the same, Nutaku is a crap money grubber page, just that. Never heard about the other one though.
