Something about Aika Online
First for classes choosing: there are six classes warrior, crusader, sniper ,dual gunner, night magician and last but not least the priest. One thing that itched you is that all classes are gender specific . So if you want to be dual gunner you have to choose female gender.
Then for the quest helper: You can click on location button and it will tell you exactly which npcs are giving quests and where the quest items lie when you are doing quests. This is a plus point in this game. but it with a boring the pve part. the dialogue with npcs is very prolongue. So you can skip it but again than you wont know where the story is heading .
In this game the interface is better you can easily put and remove things from your interface and the graphics to be surprise are reailly awesome. when you are downloading the game its only 500 MB game. What to expect from it for graphics but graphics are really good.
At last for the chat in this game. It took a noob almost 2 hours to figure out. The reason was in other games when you click whisper or general. It automatically opens that channel for you but in game you have to press" enter" command. secondly it will open a chat room type of box if you have to whisper. its big and if you are playing pvp you will likely get owned.
