My question to the "translator" is why would you try to translate a manga if you don't understand Japanese. Also judging by the quality of the translations, they weren't proofread and that leads me to believe that you aren't even good at English either. So why do it?
You know, Raven made lots of good games before COD zombie franchise. Have you tried Soldier Of Fortune? SOF 1 was great, SOF2, had a lot more guns but the game underneath wasn't as good. Before that there were Heretic and HEXEN series. Depends how far back you wanna go.
