Shaiya is a fairly straightforward game (Shaiya Money). You have a basic interface, including a small map of your skills heat it, the important role of your statistics, and your exp bar. But an interesting twist is the Bless of Goddess bar.
As players fight in PvP, killing enemies of the opposing team and capturing "Ides", they gain Bless for their realm. As the Bless bar fills, the entire realm, on any map of that realm, is bestowed extra temporary stats, such as boosted strength, less EXP lost when killed, and critical hit rate is increased. When this bar fills, the realm is bestowed with double the number and rates of the normal boosts, and critical hit rates rise off the charts. It's a great mechanic that can really ease the grinding.
Speaking of grinding, it is basically the core of the game. You do it all the time, no matter what form it's in. All you're doing is trying to get that extra level (Shaiya Powerleveling) so you can take on a few more of the same quests, and fight a few more enemies, and wear different armor.
Other Stuff - The community in general is actually pretty great. The members are VERY nice and helpful, and Aeria Games pulls an Infinity Ward move and involves their members in many events throughout their games. They even select a player to become a Game Sage which is basically an admin with reduou have to pay real money for.
