My wife introduced me to this game, tried it for a couple of hours and was caught...
Game is easy to play, most actions can be done with mouse alone, features in game are easy taught, but a few features can be difficult to understand so you get the most out of it (more about that later).
When you start the game, create your account and you have to do a "training section" which is pretty easy. When this is done, you have to decide which class your player will be, currently there are 3 classes, but more will come.
My choice was the Mage - a powerfull wizard which later transforms into either Sourcerer or Mystic, my choice was Sourcerer.
Before I go a bit deeper into the gamestyle, lets talk about spending real money in this game -
1st: Events always run, some events come every 2-3 weeks, other events every 2-3 months
2nd: You do not have to spend any real money in this game! Almost any item you see once you get in game will be available for non spenders, but it can, and will, take long time before they are on your precious character.
3rd: If you choose to spend your hard earned money on this game, things will get a lot easier/faster
If you choose to spend real money on this game, you should make a deal with yourself (or your creditcard) how much you want to spend. As I wrote a bit earlier, real money will make things a lot easier, and sometimes it's tempting to spend a "few" bucks to get that precious item - but since events are always active - you will be tempted at least twice a week.
If the game attracts you, and you want to spend money, your first choice as spender should be to activate VIP.
VIP give many nice features, one of them is "Blitz". Blitzing a dungeon means you can do it in 2-3 seconds, where non VIP's have to spend several minutes in each dungeon. Blitzing sound boring, but you have to do 80-90 tasks/dungeons every day. After a few days you will love your blitz - trust me.
You start with your main character, and after the first few quests, a beautyful Angel will join you and follow you in the future in all battles (she will later be exchanged to a stronger Angel). Soon you will defeat a knight who after the battle decides to follow and fight with you. As your main hero grows, your party will grow and you will soon have a party with one main Angel protecting and fighting for you and 4 other awesome heroes.
There is no required playtime, but there are some daily tasks you should do in order to get the most out of the game/rewards.
If you want to play the game for real, I strongly advice you to visit League of Angels forum, there are plenty of fantastic guides written by experienced players.
Mouse is your main tool for this game, in a few places your keyboard is needed, for chat, for buffs in some cross server "dungeons".
League of Angels have many servers across the world, some with many active players, some with not so many players. Make sure you select a server with lots of active players but also a server close to your own location - ask in forum. Best choice is to join a new server so you can catch up with the other players.
