Heroes of Newerth (a MOBA game, which is a really stupid term for "DotA") is having another account sale to celebrate 500k accounts!
Instead of 30$, purchasing an account is now only 10$ for a limited time!
You get the whole game with it. Every hero/item/blabla. Naturally if futures a shop, but the only thing it gives (and I'm 100% not bullshitting you on this) are cosmetic stuff (hero skins, courier skins, icons right next to your name, that sort of thing).
It gets generally favourable reviews, but I've been playing it since retail (bit over a year ago) and am still enjoying it to date.
You've probably heard people saying how it's very competitive, which is true. But it also futures "Casual Mode", which is.. Well, for casual people :). Where everyone can get gold easier to buy those shiny items to help your team kill the other team's bas!e
All in all, for 10$, no reason not to try it out. Bring friends, though, as playing with them is just THAT much better.
