I've plugged this game before but I'm doing it again now, it's that awesome. The game will be going into full release on 23 October, and will also be coming on steam. This is an action RPG, similar to Diablo 2, Torchlight, etc but much better than the hunk of shit that was Diablo 3.
Why you should play this game:
1) It's free, completely free, no charge what-so-ever. There is a shop, but that is all item effects, new skill animations, even the ability to buy/design a unique item for the game! Otherwise you can play this as much as you want for absolutely free. You can play it now!
2) It features true customisation. You really can play it any way you want to, and then there is the
passive tree, aka "skilldrasil". The tree will change with the release, since more stuff will be getting added. Last I heard it was around 1300 passives. Then there is skills, support gems and the many combinations they have. You can use fireball and make it bigger, shoot multiple fireballs, life steal off it, make it jump to nearby enemies, add cold damage, critical hit more often, make it blind enemies or shoot out more fireballs when it hits- or almost any combination of these! Every skill in the game can be modified like this.
Then on top of this is how uniques work. Most uniques have a "gimmick" and many of them are tailored to changing how a specific skill works. Good rare items are the best items but certain builds require specific uniques to work and help define them.
3) Regular updates! Usually small patches occur every week and larger content patches are frequent. The team behind this game really know their stuff and are dedicated to the project. A lot of additions are uniques designed by players, would you believe at $1000 a pop too!
4) True difficulty. Not fake difficulty where overgearing makes it go away, the mechanics mean you must pay attention. This is not a game you can just casually roll through and expect to win at high level. But when you can kill tough enemies and get awesome loot it is awesome. I guess this is also a minus, if you like Call of Duty style hand holding and coddling then this game will butt rape you hard.
5) No bots! It's true, the above point and how item dropping works means it's almost impossible to bot the game in any meaningful way. I almost never see chat bots even, and they are very quickly dealt with. Then the really crazy thing- there is no gold, coins, money at all. There are "currency" orbs, but every orb has a use in crafting. This makes it harder for RMT to really take off. Weirdly though you will be amazed at how quickly you get used to there being no money.
6) No pants!
