Shooters- WarRock : this game is basicly like black ops on crack. you an fking ride motorcycles and shoot or tanks or w.e when you sniper you can bend over atan angel and snipe behind walls only your head peeking out.
wolfteam- you can turn into wolves and humans and fight via meele combat as a wolf or with guns as a human. many game modes such as wolves vs human or wolves vs wolves or human vs human or human and wolf vs human and wolf. etc.. theirs games like last man standing, capture the flags, etc.. knife games.. the cool thing about this game is the wolves. they have special powers. 1 wolf can cling t walls and shoot at you with some weird dark magic, 1 wolf is really speedy, 1 wolf can freeze people, 1 wolf can tank, 1 wolf can turn invsible while running, 1 wolfcan turn invisible by standing still. etc.. ONLY BAD thing about this game is it's sort of laggy. or theirs cash shop items making people too good to beat. you can buy cash shop items just by killing people and getting money and trading money in for those items.
mmorpg- dragonica - dungeon based game, good graphics, not many people talk on here, gameplay is pretty fun and flashy skills, dungeons are repetitive and main way of lvling.
maplestory- 2d sidescroller, pretty easy mmorpg now that bigbang has came, easy to lvl, easy to get money, etc.. tons of players most of them are noobs or just idiots though and cry alot.
vindictus- if you like hack and slash games this is your game, ever played dynasty warriors? well this is like the free version of that. it's a dungeon based game, tons of players, gender based classes, only 3 classes for now, fun to play since basicly your just killing people, yu can basicly almost do anything and break anything in this game. you can pick up enimes and punch them or body slam them, pick up teir weps and hit them, pick up barrels or pots or w.e is lying on the ground and smash/throw it at enimes, graphics is good, collect items to make for yourself
wonderking - pretty much like maplestory mostly based on quests though.
i've played more mmorpg's and shooters but those are the only ones i found worth playing.
i would highly suggest you hit up vindictus it's too good to pass up. look up some video's online it's sick.
