I have only played Grandchase...And I think it was pretty bad....I could be wrong...But I am almost positive there is no other skills...And I played like 5 levels with people...it was so repetitious I just had to exit.
Talisman is actually pretty good. You can play it on and off. Really small client. There is no pressure to level up fast. Unique classes. Unique weapon system. Community is helpful. Good map and quest system. Good help menu. And it is just fun to play.
Lack of customization. Gender restricted classes. No regular sword wielding warrior class. Pets (non Tamer) level up by time and not kills. (This could be good or bad depending on how you feel about it.) Dated graphics. Strange art style.
