Okay, I downloaded this game and here's what I found out:
1. It's free.
2. Uhh...
I don't really understand much of how to play the game. I've killed a bunch of stuff and leveled up a couple times, but I still don't really get it. You can learn skills by leveling up your sword or whatever abilities. You level up various stats by using certain types of weapons, but it's a bit vague and confusing as to which weapons level up which stats... As far as I can guess, Swords and Blades level up Strength, Guns level up Dexterity, and Crosses and Maces level up Intelligence...
The game appears to have a class system within it divided into Warrior, Ranger, and Healer, but I couldn't figure out how to pick a class or even what it allows you to do.
All in all, I'd rather just play
Flyff.
