Been playing League of Legends a lot lately. It's essentially a remake of the Defense of the Ancients (DotA) mod for Warcraft 3 by the people that that made DotA. It's basically a tower defense strategy game where you only control one hero character, the minion characters are all AI controlled. You kill minions, other heroes, turrets and neutral monsters that hang out in the jungle between turret lanes in order to get gold to buy items to increase your character's stats. Your goal is to smash enough turrets to kill the inhibitors that prevent you from summoning the best minions, and then use those minions to assault their nexus building and win. Game modes are 3v3, 5v5, 5v5 ranked, and 3 levels of 5v5 bot games. You gain more experience for your summoner (you, the player as opposed to your champion) that you can use to build WoW-like talent trees and new spells to choose from.
The game is completely free to play. You have the option of handing them money to unlock champions faster, but you can always use the non-real money option to buy everything but skins and a few convenience items. There are ten champions that are free to play, and they rotate the free to play selection every week.
There are 70 something characters to choose from, ranging from Tanks (defense and CC oriented) to mages (usually ranged fighters that rely on abilities to get kills) to DPS (auto-attackers who mostly use abilities to set up kills or escape from being killed) to assassins (single-target attackers who can do a lot of damage to one enemy and then escape) to support (provides heals/shields and other buffs, frequently CC or damage as well).
Also worth noting, it's one of the few games I've played that goes out of it's way to punish people for swearing/afks/griefing/ or even playing modes that are out of your league. Anyone can report you after a match and then a player run (with official supervision) run system can decide to punish you based on chat logs and stats. It's actually pretty neat, unless you're a troll.
Anyway, if you're interested feel free to click my referral link or bypass me completely with 2 seconds of Googleing. My summoner name is Sergar and I'm on the US realms, if you're interested in adding me.
