I am Japanese. There are very few Japanese Counter Strike players, so I do not think many people care about this. But when Japanese is used in skin designs, I really wish people would stop using the font Meiryo (メイリオ).
For example, the AK-47 BloodSpot skin has big text that says "ライトニング". When you translate it into English, it is basically the same as writing LIGHTNING in a font like Sans or Impact. Honestly, it looks pretty lame.
I always think wow people design such cool skins, that is awesome. But seeing that kind of font choice kind of ruins it for me…
